Analog VLSI Design Lecture 32.1: Asymmetric Differential amplifier (Mismatch in resistors)

[@----700]

6:15. The common mode voltage gain formula was derived when Vx and Vy were same so we could fold and simplify the circuit . But now Vx and Vy are not same then how are you using the same formula? We can't simplify the circuit in this case and write the voltage gain formula for symmetrical condition here

From 32.1.11 and 32.1.12, only changes i.e deviation from symmetric condition is highlighted by slight deviation in terms of Delta RD. Symmetric condition formula is applicable since a small deviation from symmetric is asymmetric condition

@@InderjitSingh87 but he is asking that you have not shorted the Vx and Vy so how can you use the same formula for Vx not equal to Vy
