Abstract

This paper set up two structures model of switched-capacitor circuit based on second-order output settling, one type is charge transfer, the other is capacitance overturn. According to charge conservation when in charge storage and charge transfer process, the transfer function derived. By analyzing the time-domain solution in the form of output function, we find out the factors which influence on the rate of SC. In order to achieve the fastest settling time, the phase margin of open-loop amplifier is 63.4° in charge transfer by calculated, while in capacitance overturn is 76°.
