A common-source amplifier utilizes a MOSFET for which VA=12.5 V and is operated at VOV = 0.25V. What is the value of its (gm ro)? The amplifier feeds a load resistance RL = 15K ohm. The designer selects RD=2 RL. If it is required to realize an overall voltage gain Gv of -10V/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?
