I m designing a 2-stage miller op-amp. here in this op-amp M3-M4 are working as a current buffer. what is the effect of this current buffer on the amplifier gain? how does it affects the current distibution in the circuit? say if an o/p current of I8=800nA is flowing in the circuit then the current in the input pair of op-amp wud be I1=I2=200nA, I7=400nA, I9=800nA(without using current buffer).
Here i m attaching the circuit diagram of my op-amp.
