Abstract :
This paper introduces an alternative structure to implement damping-factor-control frequency compensation for three-stage amplifiers. A theoretical analysis is presented, and experimental results are included. From the experimental results, the new structure provides better phase margin and power supply rejection ratio but higher power consumption and larger chip area are required
