Operation Amplifier Special Design and Development

This paper reviews several design techniques and summarizes these techniques for the op-amp circuit design. New design methods are necessary for the development of op-amp in using Memristor-based compensation. In the paper, we discuss Three-Stage CMOS Op-amps., Continuous-Time Delta-Sigma Modulators, and three-stage nested miller amplifiers to work efficiently and energy-savingly, which are some good examples for describing the development of amplifiers.
