Dear friends,

Suppose I have desinged a simple single-ended two-stage miller op-amp (seen in the image below)to drive Capacitive load CL and resistive load RL with certain GBW, Gain and Slew rate.

You know we set the current in M5 to satisfy the slew rate condition, say I5= 100 µA. We set based on that current and the value of the compensation capacitor the value of (W/L)1,2.. say is 10

Now I want to convert my design to fully differential amplifier version identical to the prevoius one with same load condition. Means I will drive the same load differentially

My question, will I really get the same specification mean the same slew rate, gain and GBW if I keep the same current conditions and transistor sizes as the same from single ended counter part ?


Thank you very much
Best Regards
