Abstract
A switched capacitor input circuit that reduces nonlinear input current due to input switch charge injection. The addition of a shunt capacitor with a series switch to signal ground at the input switch of a sampling network is used to sample and hold the input switch charge injection. This input switch charge injection can then be returned as input switch channel charge during the next sampling phase eliminating the need for the input signal to supply this charge.
