Abstract :
A switched-compensation technique (SCT) is proposed for switched-capacitor circuit applications to provide fast settling performance while reducing the quiescent power consumption. The SCT can be easily implemented into flip-around switched-capacitor amplifier in which the settling time requirement is a critical index of performance. Simulation results based on a 0.13μm CMOS process are presented. Compared with a conventional switched-capacitor amplifier, a SCT-based implementation reduces the quiescent power consumption by 75% and settling time within 1% error by half.
