Abstract
A general framework for performance optimization of continuous-time OTA-C filters is presented. Efficient procedures for evaluating nonlinear distortion and noise valid for any filter of arbitrary order are developed, based on a matrix description of a general OTA-C filter model. A systematic optimization procedure using equivalence transformations is discussed. An application example of the proposed approach to optimal block sequencing and gain distribution of an 8/sup th/ order cascade Butterworth filter is given. Theoretical results are verified using transistor-level simulation with CADENCE.
