millions of such kind of circuits on EC and 99% are not fully tested. Long press to switch on does not work in this implementation.

@hurz ... your effort link here shows a N-Mosfet with an unrealistic Rds(on) of 5.7 Ohm ... you need to learn how to set mosfets yourself and stop recommending that people use mosfets with settings which are unknown and meaningless to the user.

PrathikP

You think an Rds(ON) of 5.7 ohms is unrealistic? Have you ever heard of small signal MOSFETs such as the BS170 or the 2n7000? Why don't you go take a look at their datasheets?

@PrathikP ... I agree that users need to go to the website datasheets for information ... you won't see 5 Ohm Rds(on) mentioned in the kiani library for the BS170

Good work. I always used two transistor analogy or an scr. I've always wondered how I can make a single on off switch. This is helpfull. Stop hard feelings on this circuit. It's just a representation.

@silveredken ... yes, nice presentation. To be a realistic mosfet however, the settings do need some consideration.... but full marks to the general setup.

2ctiby

@PrathikP ... Small signal mosfets can basically ignore the Rds(on) which is to do with full Ohmic switching, so 5 Ohm makes no difference once we are in saturation for small signal amplification. In Saturation, as used for small signals, another type of resistance occurs, called the 'drain output resistance' which in the case of this presentation is over 34k Ohm. (hence forget 5 Ohm). This presentation is about full Ohmic switching, not Saturation small signal following, and the hurz alteration correctly ensured that Ohmic occured rather than Saturation. By doing so, hurz should have used a suitable mosfet with a low Rds(on) and not a small signal type of mosfet. Hurz has not specified a mosfet ref. number for his alteration, but his Rds(on) is not of a type which is suitable for full Ohmic switching.

"you won't see 5 Ohm Rds(on) mentioned in the kiani library for the BS170". Dear @2ignorent2be, please open your eyes wide - buy glasses if you need to - and take a closer look at the MOSFET library. The Rds(ON) is mentioned for every MOSFET.

By the way @2hillbilly do you really think that anyone takes you seriously? Lol you are such a joke. Spamming the comments section all the time you uneducated fool.

PrathikP

6 years ago

It is understood that the values of Rds in the library are the Rds(on) values, because any other value is useless. Now just because kiani has used the "registered" symbol next the the resistance values, are you going to think that all the on resistances are registered? Probably you are, given your low intellect and incompetence

@prat ... you have no idea about how to calculate drain current, Rds(on), 'drain output resistance' etc... you are a joke on EC ... why don't you just stay quiet instead of presenting your nonsense? ... it was only a few weeks back that you said that datasheets do not show Vgs etc... how can you live with yourself in such stupidity.... Now let's take it one step at a time: 1: How do you calculate Rds(on) in any mosfet circuit ? ... you just have absolutely no idea! ... step 2: What is meant by 'drain output resistance'? ... you have no idea ... google it and then come back with technical discussion instead of your infantile insults.

2ctiby

Simply ....... What is your own estimated Rds(on) of this Nmos presentation? ..... and what is the Rds(on) of the hurz Nmos link presentation ...... Let's discuss each technical answer sensibly... Insults or technical will show where an individual stands.

Dear @2inept2be, you think that a MOSFET with an Rds(ON) of 5ohms is impossible and you're calling me a joke!? Lol, you're the joke. Hell, you're the circus clown of EC. And you are changing the topic to the formula of drain current!? What is that going to achieve!?

2ctiby

6 years ago

@prat... I did not say that mosfets with 5 Ohm do not exist ... I said that 5 Ohm for a full switching mosfet is unnecessarily high. You are incapable of reading, as well as you not being able to calculate a Mosfet Rds(on) etc. Regarding drain current: When it alters, it changes the voltage between the divider resistors here which in turn alters the voltage for turning on/off mosfet gate. Why do you pretend to know about mosfets when you are completely clueless?

My technical reference is in this circuit you still wonder about and cant understand, there is nothing to say about it. So we see after 2 weeks of silent you are back to get your dosis of trolling. @2dumb2be... Learn how to setup correct Mosfet so they fit to real ones, which you never had in your hands. When it comes to electronics the community will note that 2cent can never discuss technical nor he is able to make circuits.... he only every spouts abuse to hide his zero ability. Check the spec of BS170, read first, then ask! But @2cent with is big ugly nauty mouth must again open it and talking CRAP

2ctiby

BS170 is a small signal mosfet as described on the datasheet ... That means that it is most suitable for signal following in Saturation state. In Saturation state the Rds(on) of the mosfet may be generally higher than that of a full switching mosfet, since in Saturation, the Rds(on) is basically insignificant compared to the now found 'drain output resistance' which is generally much higher than Rds(on). ... This presentation here is about Ohmic full switching, not signal following ... The hurz choice of BS170 signal follower with its high Rds(on) was a poor choice ... not surprising, because hurz has no idea what 'drain output resistance' is about or how to calculate it and account for it when designing mosfet circuits. It is a pity that he insists on pretending to know all aspects of electronics rather than asking. Instead, he resorts to abuse.

@kiani... you have no idea about mosfet current analysis and you have never even started with Saturation drain output resistance... so I suggest that you learn how to find your drain current in that circuit of yours from about 6 months ago before you embarrass yourself further.... just stick to technical points instead of insults if you are looking for any credibility on EC.

kiani

Also Rd(on) is different to Rds(0n).

2ctiby

@kiani ... that is crap ... you obviously are unable to explain just what Rds(on) means ... so instead you divert with nonsense ... Now declare mathematically what you think Rds(on) means, otherwise you will continue to be the laughing stock which you are at the moment. If you declare it properly as you think, then I will give you due respect and explain exactly what it means without scorn.

@kiani .. nothing more to say to you, go away for another 6 months now, and then we will see if you are any closer to being able to understand and calculate mosfet drain current... sad case.... meanwhile, look at Vds= id×Rds and wonder why sometimes it gives the same result as the mathematical calculation of Rds(on) and sometimes not.... pity you are too stubborn to ask why politely, whereby you could understand it all within minutes instead of seeking for years.

@PrathikP ... Neither you nor kiani nor hurz have ever come across how to deal with Mosfet resistance in the Saturation state ... and I don't intend to explain it to such three idiots ... My only advice is that you keep quiet and not embarrass yourself any further. Now go and google 'Mosfet drain output resistance' and then we can all wait to see which of you three stooges casually comes back first in a week or so pretending that they have known it all for years.

After decades Mosfets are on the market he starts today and thinks he is the only one ever watch into its behaviour. Wow, how naive this this guy is. @2cent Stop your propaganda against person you dont know. Do your staff private and if you have quiestions open your own fun thread. But stop your nazi propaganda. Or you get reported if i see my name in it, got it? I habe references you dont have. You dont have to take care, your name is already dirty, but stop trow with mud on other user who have a reference in electronics, that by far not your competence. You measure four voltages where only three are physical possible. You have biggest problems addapting PMos and its voltages. Your negative resistance at pin3 of 555 is still a morical for you and is explained ridiculous. You messup circuits and dont understand why an ohmeter is helpful. Your competence in electronic is not based on the help you dont give to other users. You dont have any reference. So stop your nazi like propaganda or it will rain reports for you.

You alread understand you were talking bullshit, right? Isn't it better to say im sorry im inexperienced and have not understand the circuit? No you start a new topic and be a nazi and attack all who told you how wrong you are in your technical statements! Learn learn learn, do pratice practice practice!

2ctiby

@hurz ... Firstly I will remind you about my 'fun with mosfets' article from year 2016 which mentions mosfet saturation in detail... it is new to you, not me.... and it is you who must now learn to account for the 'drain output resistance' which you have never heard of until now. The BS170 datasheet tells us that it is a small signal mosfet (for such saturation purposes) and so has a relatively higher Rds(on) than general switching mosfets. Your choice of that higher Rds(on) type of small signal mosfet was not a good choice compared to most general switching mosfets which have an Rds(on) below 1 Ohm and which could suitably be used if a higher current were required. You should accept my technical discussion here and not consider it to be spam or trolling or aggressive etc. Now that I have introduced you to saturation drain output resistance, you should start to learn how to calculate it, along with learning how to calculate Ohmic Rds(on) without you having to draw circuits which contain an Ohm meter. Firstly then, you need to stop pretending that you know all these things already.

hurz

6 years ago

You are not experienced enough to tell anybody what to use or not use. You continue your nazi propaganda style and i will report that. BS170 IS PERFECT for this job and you epic fail again! blame other will not help you to look stupid! As more you try to shift you incompetence to other users with references you look more and more stupid. How long is the list of users you tell them THEY DONT KNOW? While you measure four voltages where physical are only three available till today you are stubborn enough to not see your incompetence. So stop to tell PrathikP and me and many more we "dont know", you make yourself to the community clown. Where are your references, when have you helped users to understand circuits. You have big issues in PMos understanding and its voltages, really big issues. You mess up any circuit. You do not understand the most simple basics in electronics. So better shutup. Here your last arrognat words based on zero references go ahead lets see how arrogant you can be, the adims are listening:

@2cent, you always forget we engineers are around for decades and we went through all these topics, also mosfets, there are thousands of thing we have seen and learned while you scratches at the surface for years at the same point Mosfets. You are standing still and have still questions, you still look at the same fomulas. Formulas you watch for years are around for decades and you still dont get them? Is there anything new for you, you can still discover? Wow, take your time.... you seems to need a lot. JFets you totaly missed as we all noticed a few weeks ago.

2ctiby

@hurz ... That last year extra current that keeps troubling you is due to the creation of current due to the sudden change of voltage at the cap instant switching ... it is described by calculus, but you were unable to absorb my description. There is no point in me saying it again... you will just have to accept your inability to comprehend such things. I suppose you would like to refer to that as aggressive spam and report it lol. Fact is hurz, you don't even know what current really is ... you think that it is just 'the movement of electrons', but you would not learn from me if I were to explain it in more detail so that you could understand it better. You are deluded in to thinking that you already know better than anyone in all things. People with that condition can not be helped unless they have an inner turn-around from that self delusion. Regarding your BS170... yes it can work fine, but I was drawing attention to the fact that a switching mosfet which has an Rds(on) of less than 1 Ohm would be a more natural choice ... but you were not in a position to understand why I would say that because you had no idea about the concept of drain output resistance and its relation to a small signal mosfet ... it's a pity that you prefer to report people as being trolls etc instead of being able to discuss technical matters sensibly.

hurz

Well, we know a lot more then you @2cent, we are much longer in that business, and for some reasons we are faster in adapting new things, while you need years to get there.

@hurz ... When you first learned about electronics there were no Mosfets generally on sale, so you can forget the angle of having learned about mosfets as a teenager. ... You have also demonstrated here on EC that you have very limited mosfet knowledge, so you really do need to learn ... but still you try to give the impression that you know all things already ... you have not even learned to calculate Ohmic Rds(on) without an Ohm meter yet, let alone resistance in Saturation ... I suspect that you will be burning a lot of midnight oil for a while, then we will see you back here talking oh so casually about how to make these calculations .

Then you must learn this first. Dont think you can stand still there is ever day something new to learn. Dont waste 4 years (since 2016) to watch the same formula, you will fall back.
