Abstract :
A theoretical evaluation of high-frequency distortion of three-stage amplifiers adopting the reversed nested Miller compensation is presented. The inherent computation complexity is reduced by exploiting a suitable amplifier model, and the nonlinear contribution of each stage is enucleated. Transistor-level simulations on a CMOS circuit are found to be in very good agreement with expected results.
