I need to drive the nmos differential pair of an op amp. Method i know is to give input common mode voltage. is there any way without that because, previous module in our project is charge scaling capacitive DAC. where only step changes occur like 0.45v, .9v, 1.35v. inputs to differential pair are analog signal and converted analog signal from DAC. so the differential input pair transistors are not in saturation.
I can provide schematic if needed.
