This paper presents a sampling technique with reduced distortion for use in a sample-and-hold circuit for high resolution analog-to-digital converters and switched capacitor filters. The technique involves bootstrapping both the gate and the bulk terminal of the sampling switch to improve linearity. Circuit implementation and SPICE level simulation results are presented.
