Unformatted text preview: specification. 3. For the common source amplifier I picked a bias point of 1ua, this resulted in a gm=Sqrt(2*un*cox*(W/L)*Ibias)=2.651E-10 and RT to be RL||Rds. 4. For this circuit I removed the transistor and replaced it with a switch. The switches parameters are vout=.5 vin=3 ron=1E3 roff=1E8 to model the switch in SPICE. I found gm to be change in voltage over the change in current which is VGS-VDS/ I, and RT to be RL||rds, which is (1/RL+1/rds)^-1....
