Response to the following problem:
A common-source amplifier utilizes a MOSFET operated at VOV = 0.25 V. The amplifier feeds a load resistance RL = 15 kΩ. The designer selects RD = 2RL. If it is required to realize an overall voltage gain Gv of -10 V/V what gm is needed? Also specify the bias current ID. If, to increase the output signal swing, RD is reduced to RD = RL, what does Gv become?
