The performance of several switched-capacitor (SC) integrators is compared, and a description representation is introduced. Offset-compensated circuits which reduce the capacitance spread in very large time-constant SC integrators are presented. The theoretical equations are derived for all SC circuits and are then confirmed by simulations.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>
