Abstract

A charge transfer circuit includes an input terminal for receiving an input electrical charge, a transconductance amplifier having first and second inputs including an inverting input, and first and second differential current outputs, and a multiple output stage circuit responsive to the differential current outputs for producing two or more electrical current output signals whose values are related to the values of the differential current outputs and to each other. Also included is a feedback loop for delivering one of the electrical current output signals to the inverting input of the transconductance amplifier, and an integrator for integrating another of the electrical current output signals to produce an output electrical charge whose value is related to the value of the input electrical charge.
