一种13bit40MS/s采样保持电路设计
Design of a 13 bit 40 MS/s sample-and-hold circuit
摘要
Abstract
A 13 bit 40 MS/s sample-and-hold circuit for the pipelined A/D converters is designed. Capacitor flip-around ar- chitecture and gain-boosting folded cascade operational transconductance amplifier are adopted to achieve high resolution and resolu- tion. In order to reduce the nonlinearity related to input signal, a bootstrapped switch is used. The S/H circuit is designed and simulated in TSMC's 0. 18 μm CMOS process at 3.3V supply voltage. Simulation results show that SNDR of 84.8dB and SFDR of 92 dB are achieved at 40 MHz sampling rate.关键词
