Abstract :
A high-performance bootstrap switch for low-voltage switched-capacitor (SC) circuits is presented. The switch enables the precise sampling of input signals on a low voltage supply with high speed, low nonlinear distortion. Experimental results in TSMC 130nm CMOS process show that a peak signal-to-noise-and-distortion ratio (SNDR) of 102.8 dB, spurious-free dynamic range (SFDR) of 104.6 dB and total harmonic distortion (THD) of 105 dB can be acquired at 125 MSample/s.
