High performance multirate SC circuits with predictive correlated double sampling technique

This paper proposes the design of multirate switched-capacitor (SC) filters with the employment of the predictive correlated double sampling (CDS) as a means of achieving higher accuracy, good linearity and higher dynamic range as well as lower power dissipation for high frequency and/or low voltage CMOS applications. Such a new technique will be first explored by proposing the novel fundamental building blocks: unit delay circuit and accumulator for multirate SC circuits with the reduction of the effects of op-amp imperfections with respect to the input referred DC offset voltage, 1/f noise as well as finite gain, and then be consolidated by implementing a specific video application
