A Behavior Model of Discrete Sampling and Hold Amplifier based on AC Response

Authors: Wang Xing-hua, Zhong Shun-an, Zhang Zhuo


A kind of behavior model for discrete sampling and hold amplifier with charge transmission is analyzed. The transfer function and behavior features are based on the main AC responses of operation amplifier. The result used in pipelined and sigma-delta ADC shows the exact of model of sampling and hold amplifier, and the non-ideal factors are taken into account.

Keywords: SHA, response, behavior, transfer function.
