摘要

提出了一种用于低压开关电容(SC)电路的高性能自举开关。该开关能够在低电压电源上对输入信号进行精确采样，具有高速，低非线性失真。实验结果表明，在TSMC 130nm CMOS工艺下，在125 MSample/s下可获得峰值信噪比(SNDR) 102.8 dB，无杂散动态范围(SFDR) 104.6 dB，总谐波失真(THD) 105 dB。

A high-performance bootstrap switch for low voltage switched-capacitor circuits

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.
