Abstract
This paper describes the design of switched-capacitor (SC) filters by the use of a discrete integrator called the composite discrete integrator (CDI). Despite the fact that the CDI is more complicated than well-known integrators such as the bilinear discrete integrator (BDI) and the lossless discrete integrator (LDI), it offers high frequency advantages by minimizing discrete integrator errors. Cascade, inverse-follow-the-leader-feedback (IFLF), and ladder filter design techniques are presented. Simulation results of the filter examples are also given.
