MOSFET

(a) Draw an n-channel MOSFET showing the source, drain, gate, and body contacts.

(b) How should this MOSFET be biased so that it is in the saturation regime?

(c) How does the drain current depend on the gate voltage in the saturation regime?

(d) How do you calculate the maximum frequency at which a MOSFET operates? About what frequency is this?
