Estimation of Dynamic Range in High-Order Transconductance-Capacitor (G{sub}m-C) Filters

摘要

A method of noise and nonlinear distortion analysis in high-order G{sub}m-C filters is presented. It allows an estimation of the filter dynamic range when the type of transconductor and the filter passive prototype are chosen. Non-linear analysis is based on Volterra series approach. Calculation results are in a good agreement with computer simulations and experiment.
