QUESTION:

A CS amplifier utilizes a MOSFET with nCo x = 400 A/V2 and W/L = 10. It is biased at ID = 320 A and uses RD = 10 k. Find Rin, Av o, and Ro. Also, if a load resistance of 10 k is connected to the output, what overall voltage gain Gv is realized? Now, if a 0.2-V peak sine-wave signal is required at the output, what must the peak amplitude of vsig be? 7
