Abstract :
This article presents a current signal sample-and-hold (S/H) circuit using 0.5 mum CMOS technology. A current minimum circuit is used to sample the input signal in place of a sampling switch used in the conventional S/H circuit. The current peak detector is used to hold the signal from the minimum circuit in the "hold" state. The proposed configuration is adopted effectively to cancel switch feedthrough error. The performances of the proposed circuit are demonstrated using the PSPICE analog simulation program. Simulation results show the sampling frequency up to 100 MHz and high accuracy.
