Bootstrapped circuit suitable for switched capacitor circuits

This paper proposes a bootstrapped circuit to decrease the on-resistance independent of input signal dependence and bulk effect. Currently, the circuit can choke back the charge distortion between the path of precharge capacitor and gate terminal of signal switch. By HSPICE simulation with 0.13 μm 1.2 V/2.5 V CMOS process, this circuit is proved to be suitable for the switched capacitor circuit.
