Razavi Electronics 1, Lec 29, Intro. to MOSFETs
MOSFETsthreshold voltagesaturation
What this lecture covers
Razavi introduces the MOSFET from the ground up — structure, channel formation, threshold voltage, and the move from triode into saturation. A clean derivation aimed at building design intuition rather than memorizing equations.
Why watch
The single best on-ramp to transistor-level analog design — every CMOS stage later depends on this model.
Skip if
You already derive the square-law I–V from memory and know why saturation makes a good amplifier.
Best timestamps
- 4:00 Physical structure of the MOSFET and the role of the gate oxide verified verified high confidence
- 25:00 Channel formation and the meaning of threshold voltage high confidence
- 52:00 Triode vs. saturation: where the device becomes a good amplifier medium confidence
