How do VD MZ and Vout2 change if Vin1 slightly increases wit

How do V_D MZ and V_out2 change if V_in1 slightly increases with respect to V_in2? How would the \"the circuit\" be affected (gain, common mode voltage, output voltage swing, etc.) if the power supply (3v) was lowered to1v? Discuss the maximum input voltage swing considering common source stage transistors (M_5 and M_6) will still be in saturation all the time?

Solution

1. Vin1 > Vin2

VDout = VGS + Vout2

Vin2 decreases

both VDout ,Vout2 decreases

2. if power supply reduces

gain= Vout / Vin also reduces

common mode voltage unchanged

3. Vin max = vin1 + vin2
