Consider the following common source amplifier with a current mirror load (the textbook refers to this as the "basic gain cell"). quiz4_fig1.jpg Assume the following process parameters: Vtn = |Vtp| = 0.5V kn' = 1 mA/V2 kp' = 500 A/V2 IREF=300A and (W/L)Q1=10, (W/L)Q2=10, (W/L)Q3=15 gm1=2.0mA/V Find the voltage gain, Av, if you are given the Early voltages are: VAn=20V (NMOS) |VAp|=5V (PMOS)
