Problem 3:
A MOSFET is connected in the source-follower configuration and employed as the output stage of a cascade amplifier. It is required to provide an output resistance of 200. If the MOSFET has kn'=0.4mAV and is operated at Vov=0.25V, find the required WL ratio. Also specify the dc bias current ID. If the amplifier load resistance varies over the range 1k to 10k, what is the range of Gv of the source follower?
