Design and Analysis of Three-Stage Amplifier for Driving pF-to-nF Capacitive Load Based on Local <i>Q</i>-Factor Control and Cascode Miller Compensation Techniques

This paper presents a new frequency compensation approach for three-stage amplifiers driving a pF-to-nF capacitive load. Thanks to the cascode Miller compensation, the non-dominant complex pole frequency is extended effectively, and the physical size of the compensation capacitors is also reduced. A...
