Analogue switching with transistors

146

01:40:00

Switching with MOSFETs. With the addition of the capacitors here, these are "sample and hold" or "track and hold" circuits.

Note how the single-NMOS switch doesn't turn on fully when the input is more than about half the "on" gate voltage, and fails to turn off when the input is more negative than the "off" voltage.

The two-FET switch always turns on fully, but fails to turn off when the input exceeds either gate voltage.

Give me a predicament where this circuit would be typically useful? Cretin. Kill yourself

Are you serious @roops1967? You are talking to someone legitimately classed as a minor, as such - and are of three times this young man's age whilst trying to sling out accusations like that .... You seem to be trying to wrangle you're way out of being found out .. Especially to say you have hacked him

@geoffgoldstein: Are you serious? Have you not seen markusblacks comments and his "work"? He's a thoroughly nasty piece of work himself. I thought of giving him some sound advice from my experience, but now I don't think I'll bother.
