Where is the body diode

152

00:54:22

There is no body diode in Everycircuit
In real life mosfets have a body diode that conducts from source to drain, the gate has no control of this diode. 

This example shows 100VDC applied from source to drain of a nmos fet (wired backwards). Current flow is negligible (1nA). 

Two conclusions from mosfet testing, forward and backwards.
1. There is no body diode from source to drain.
2. There are two body diodes, one source to drain, the other anti parallel from drain to source.
The test results are indisputable. No body diode.

Swap the drain and source and you'll see what I'm talking about. And i clearly said in the discription "I'd like to know what the deal is with this body diode". Didn't say that there's a proper body diode. Again, read properly.

By the way you don't need an ammeter. Probing the source is sufficient

I used a sine wave. A square wave/ triangle wave can also be used. Just incase the clarification is needed

Like i said in my post, this "diode" doesn't always work.

You have been clearly told by me and hurz multiple times. The is no fucking diode. I don't care what you are try to gain in yourself or try to steal from others. You not getting it from me. Stop instructing ignorance, this is the second subject you have LeButched up in a month.

And how many time are you going to rewrite your discription lol? I think you realised that the previous version didn't make any sense!

And you changed your discription yet again

I changed the description by only adding the link to your circuit. You cannot accept the facts of the simulation. There is no "mosfet body diode". You apply different waveforms and measure the source and see gate capacitance, playing around in your sand box with jacked up sim speeds. What did you expect? That's why I'm measuring the mosfet, and not the mosfet and the gate with a bunch of bs. 1uA produced from gate capacitance, only 1nA through the body.

Shouldn't you try to look into another explanation? Inaccurate results from ringing, simspeed. Wtfc?

PrathikP

Lol it has nothing to do with the simspeed. Or the gate capacitance. And both you and i know that you didn't just add a link. You changed the text cause even you realised that it was stupid. And where did source and gate capacitance come from? Are we even talking about the same thing are or are you just seeing things?

Your cry for attention didn't work rich. This discussion didn't need a new thread, yet you created one in the vain hope that some one would help you poor puppy. Not gonna happen in a million years.

And i still don't understand why you cannot open your eyes and read properly. Again, i said that in a certain configuration, the D to S path shows "diode-like characteristics". I quite clearly said that. And i also said "I'd like to know what the deal is with this". Even if i tell you a 1000 times, you will still think that I'm saying that there's a perfect diode, even though I'm not.

And what's that idiotic theory of yours? "Ringing" or "simspeed" cannot affect my results in any way. Do you even know what ringing looks like.

rich11292000

I didn't say there is a perfect diode. I have no clue what you can't comprehend other than there is no "mosfet body diode". You have only showed normal mosfet operation up to this point. Hurz stepped in twice on your other circuit, but you ignore him too. Just imagine all the things your wrong about in life because you think your Mr. Right.

I know you didn't say that there is a perfect diode use autistic creature. Here's what i said: And i still don't understand why you cannot open your eyes and read properly.

Read again. Properly. Open your eyes. Stop saying random things. You say ringing might have lead me to misunderstand the simulation. Why do you say that? You clearly don't even know what ringing is and what causes it. You're just throwing in random technical terms to make yourself look like a smarty pants. Oh just grow up you attention seeking kid. The very fact that you started a new thread just goes to show that you're some attention seeking idiot without anything better to do.

Here, let me quote the last part of that comment again: Even if i tell you a 1000 times, you will still think that I'm saying that there's a perfect diode, even though I'm not.

This comment of yours doesn't make sense too: You apply different waveforms and measure the source and see gate capacitance, playing around in your sand box with jacked up sim speeds.

I told you 3 days ago, Hurz told you 3 days ago, I have provided a link to a previous discussion. There is not a "mosfet body diode."

You comment says "D to S path shows "diode-like characteristics"." AGAIN there is only "mosfet characteristics" READ! Use the search button before you invent fairy dust.

Don't you see the diode like characteristics? Yes, you do. You do see it. Very well, in fact. You are just like any other immature teenager who doesn't like admitting that their wrong. Clearly.

You are just some ignorant child. You say that this is ringing!? You say that this is some sim speed error!? You are brain dead, dude.

rich11292000

You have only dismissed the fact that there is not a "mosfet body diode" in the simulation. Your circuit still has in its title "mosfet body diode", you attempt to describe these characteristics of "this diode" in the circuit description. You speak of "THIS"THIS"THIS", "this" doesn't exist.

PrathikP

By this do you mean your brain? In that case, yes, it doesn't exist

You know at this point it kinda looks as though you just want to drop the last comment, cause your comments make lesser and lesser sense by the day. Fine, I'll let you have the satisfaction.

'Your circuit still has in its title "mosfet body diode" ' lol this is just another piece of evidence that you don't read properly. Didn't you see the words "curious" and "case"? Probably not, cause you only see what you wanna see.
