Abstract :
A novel design method for low power switched capacitor (SC) circuits is presented. The new SC circuits make the best use of the characteristics of switched-capacitor circuits and can be directly powered by an alternative-current (AC) power supply. Compared with the traditional direct-current-powered SC (DCPSC) circuits, AC-powered SC (ACPSC) circuits achieve a power saving ratio up to 40% without obvious damage to the settling behavior, which is simulated and fabricated with CSMC 5-V 0.61 μm technology.
