Abstract
This paper introduces new charge and discharge paths to speed up the turn-on and turn-off process of bootstrapped switch. In the mean time, linearity is improved without increasing capacitance or area. The proposed switch is designed in SMIC 65nm CMOS process and the results indicate that total harmonic distortion (THD) of 95dB is acquired when 103MHz input signal is sampled at 1Gsps.
