Thank you so much for this EXCEPTIONALLY well explained video. 13mins to explain a 1hr 30mins Uni lecture. You're gm is super high

If anyone is wondering how he got the 2nd and 3rd form of gm: from the saturation current equation we get (Vgs-Vt) = √((2*id)/(un*Cox*W)/L) also (un*Cox*W)/L = 2*I'd/(Vgs-Vt)^2 Now from the first gm equation the 2nd and 3rd form can be achieved.

thank youuuuu this ties everything together. My prof didn't exactly give us a definition of transconductance, so your efficiency analogy really helped.

just want to say thank you, im a research chemist who recently started working with some electrical engineers on III-V devices. Having no prior knowladge you've thought me some basics so i can communicate with them. sencerely, thanks.

In first equation gm proportion to Vgs-Vth and in 3rd equation it is inversely proportion to Vgs-Vth. How can this happen at the same time ?

Why do we consider gm only for saturation mode, and not for linear mode?

Sorry, but why do you need to know the transconductance of a MOSFET in the triode or the linear region?

How did you get second and third form of Gm?
@lukeangel19748 жыл бұрын
how come at the start of the video gm=Id/Gs and at the end of the video gm=2Id/Gs-Gt. Gt is just a constant.

Might sound a little dumb but, do the equations differ in the case of PMOS, as compared to the NMOS? Great videos btw

The equation is "valid" for the both (PMOS and NMOS) devices. It should be noted, that these equations is not generally accurate/valid (especially for submicron technologies).
