A deterministic and stochastic signal analysis is presented on switched capacitor filters. This relatively new discrete-time circuit design technology provides a wide field of applications in the areas of filters, circuitry, and communications. It also raises numerous problems and challenges in both discrete-time design implementation and noise analysis. Basic principles of switched capacitor integration/summation networks and their interfacing is first presented. A review of fundamental discrete-time system design techniques which are, and can be, adopted in the design of switched capacitor filters is then provided along with a discussion of frequency design criteria to deal with frequency warping and aliasing effects. An analysis of computer and test results of a 7th-order bilinear and an 8th-order LDI leapfrog switched capacitor lowpass filter is then presented. Finally, with the intent of presenting an alternative approach to current analytical procedures in switched capacitor noise spectrum analysis, various spectrum estimation techniques are presented along with test results of noise spectrum estimation of a typical switched capacitor integration circuit. / M.S.
