(How many floors, which transistor is useful, etc.) C1 capacitor is required for simulation. It is not an element that you need to add to your calculations in hand calculations or analysis. B) Perform DC analysis. Find the current and voltage in each arm. C) Calculate small signal gain Vo/(V+-V-). D) Calculate CMRR. (When calculating CMRR, you can think of M4 as a diode-connected transistor and converge to a difference resistor CMRR with a normal resistor.) Does the second floor affect CMRR? 1) Parameter for mosfet : VTHI=1 V, uncox=200 A/V2, upcox=100 A/V2, An= Ap=0.02 V-1. Use a single 5V power supply for VDD.
