Abstract :
In this paper, a new method to compensate three stage amplifier is proposed, second non-dominant pole cancellation of multi-path nested Miller compensation (MNMC) are paid. Using the feed forward signal and changing the location of the second zero, second non-dominant pole is removed and behavior of system is approached to the first order system. To verify the method, one practical example is presented in 0.18 um CMOS technology. The simulation results confirm effectiveness of proposed method to compensate three-stage amplifier.
