Hello,
I used Behzad Razavi's book to design a fully differential telescopic op-amp [screenshot attached]. Then I follow the same steps to design my proposed opamp, but I am not getting the desired result. Can someone point out where I'm doing mistakes?
For your reference, I have attached hand calculation and simulation screenshots. Thanks
My design specifications are: Supply voltage: Vdd=5V, Output voltage swing: 5V, Power ≤ 5mW, Gain: 500, UnCox= 151uA/V2, UpCox: 26uA/V2, Vthn=0.84V, Vthp: |1V| .
