Abstract

Private and mutual compensation circuits in symmetric stages CMOS operational amplifiers

  The paper discusses the features of their own circuits and mutual compensation circuitry in a differential stage in CMOS transistors. It is shown that their composition can significantly increase the differential gain in symmetric cascades with a dynamic load, significantly reduce common mode gain and extend the range of operating frequencies. As an example, the evolution of the basic concept of a symmetric stage and the results of its simulation in Cadence Virtuoso.
