Hello guys
in the CMOS operational amplifier, we design it in all the transistors to be in sat region and we consider it as the linear region of amplifier operation. then after that we say this op-amp has non linearity problem because of the non linear relationship between the voltages and current in the cmos transistor and this what I am got confused.
in the second part of my question, in the very high gain Op-amp (>=80db) the range of the differental voltage is very very small in terms if several mV, so how like this range is suffering from the nonlinearity ??
Thank you all previously for your coming participation. and please if you have an articles it will be very helpful
