Abstract

An MOS FET circuit with a summing circuit at the input of an amplifier to provide charge cancellation. The summing circuit is capacitively coupled to the input with a charge cancellation capacitor. A separate amplifier, having components substantially the same as the components of the first amplifier, is connected through the charge cancellation capacitor to the first amplifier.
