This paper describes the design of a switched capacitor ladder filter and explores the optimization of the Opamps for reducing power consumption. A rough but quick optimization method of the opamp is suggested depending on the settling requirement for a desired accuracy. A method for approximately analyzing the noise in different types of switched capacitor circuits is also presented. The results are compared with simulations and exhibit a close match. A prototype filter has been laid out in a .25um process and has been sent for fabrication.
