A Common-Source amplifier utilizes a MOSFET with µnCox = 400µA/V2, W/L = 10, and VA = 10V. It is biased at ID = 0.2 mA and uses RD = 6 k-ohm. Find Rin, Avo and Ro. Also, if a load resistance of 10k-ohm is connected to the output, what overall voltage gain Gv is realized? Now, what if a 0.2V peak sine-wave signal is required at the output, what must the peak amplitude of vsig be?
An amplitude modulated amplifier has a radio frequency output of 50w at 100% modulation. The internal loss in the modulator is low. What output power is required from the modulator.
