You senstence is interesting. You want increase the gain and cut power at the same time. Actually, you have not specify what you are currently in your design. If you currently have dc gain 40dB and want increase to 60dB. It is easy. But if you are look for 120+ dB gain. It is much more difficult. You can read some opamp book and study high gain opamp design.
Thank you.
Currently the gain is 113 dB. From that, I have to design with improvement of 30% gain. The supply current is about 1.2mA and need to be decreased about 30%.
One more thing, the phase margin target is 60 degrees.
I would like to know the easiest way to calculate the phase margin.
