    How to improve the PSR of my fully differential op?

    Got it. But now what I am really talking about is PSR=Avdd, NOT PSRR. So consider my fully differential op-amp, the single-end PSR is not related to the Open Loop Gain. Am I right?

    How to improve the PSR of my fully differential op?

    thank you, erikl. But I don't understand how PSR is realted to loopGain, can you explain that? I wondered whether PSR is related to Rout and prasitic capacitor from vdd to Vout? Thank you!

    biasing circuit question from berkeley ee240

    Use an opamp can make the vds of M1 equal to the voltage of V0. Notice the circuit use negative feedback, so the opamp will help to set the quiesent point.

    How to improve the PSR of my fully differential op?

    Hello, everyone. I am now designing a Class AB folded cascode fully differential opamp, and the Class AB is implemented by floating voltage source. The spec require a PSR(Avdd=Vo/Vdd) of single end less than -50dB, but I can only get about -46dB in tt corner. Here is my question: 1. How to...

    How to design a high speed high precision op-amp?

    Hi, guys. If you need to design a high speed high precision op-amp, what architecture will you choose, and how to make the trade off? This question is bothering me, thanks for answering.
