Abstract
A switched capacitor integrator system includes an input cascoded amplifier circuit; a summing junction; an integrating switched capacitor circuit connected to the output of the input cascoded amplifier circuit and to the summing junction; the integrating switched capacitor circuit including an input switched capacitor circuit responsive to an input and connected to the summing junction; and a correlated double sampling capacitor circuit including an offset capacitor interconnected between the summing junction and the input of the input cascoded amplifier circuit.
