A new performance-boosting frequency compensation technique is presented, named Transconductance with Capacitances Feedback Compensation (TCFC). A transconductance stage and two capacitors introduce negative feedback to a three-stage amplifier, which significantly improves the performance such as gain-bandwidth product, slew rate, stability and sensitivity. An optimized TCFC amplifier has been implemented, and fabricated in a 0.35-μm CMOS process. The TCFC amplifier driving a 150-pF load capacitor achieved 2.9-MHz gain-bandwidth product dissipating only 45-μW power with a 1.5 V supply, which shows a significant improvement in MHz·pF/mA performance.
