Title: CMOS track and hold amplifier

Abstract: A switched Capacitor Track and Hold Amplifier having at least one signal input, at least one clock input and an output, comprising a sampling capacitor, a buffer amplifier connected between the input signal and the first plate of the sampling capacitor having high output impedance in the odd clock phase, a switch connected between the second plate of the sampling capacitor and a signal ground being closed in the even clock phase, means for copying the sampled input voltage to the output in the hold phase and means for controlling the output impedance of the input buffer amplifiers.
