Abstract
This letter presents a low-distortion bootstrapped switch for improving sampling network linearity. The dynamically driven gate approach and the dynamically driven deep N-well technique are proposed to reduce the parasitic capacitance at crucial nodes. Simulated in a 180 nm CMOS process, the proposed switch achieves a total harmonic distortion (THD) of −101.3 dB at an 80 MHz sampling frequency. This is a 20.7 dB increase in THD over the conventional switch.
