A common source amplifier utilizes a mosfet for which Va= 12.5 V and is operated at Vov= .25V. What is the value of (gmro)? The amplifier feed a load resistance RL= 15Kohms. The designer selects RD=2RL. If its required to realizes an overall voltage gain Gv of -10 V/V, what gm is needed? Also Specify the bias current ID. If to increase the output swing, RD is reduced to RD =RL, what does Gv become?
