Nonlinear distortions in SC-integrators due to nonideal switches and amplifiers

An investigation is made of the nonlinear distortions that arise in high-frequency MOS SC (switched-capacitor) circuits due to the slewing of the amplifiers and the nonlinear resistances of the MOS-transistor switches. Simple models for the switches and the amplifiers are developed and applied to determine the resulting distortions in a commonly used SC integrator. The results are the basis for investigating more complex circuits that use the integrator as a building block.<
