Abstract :
An approach to the systematic analysis of switched current-filters is described. The proposed technique is based on the nodal analysis of a purely resistive network that models accurately the behavior of the filter for small signals, allowing the use of any practical topology and the inclusion of important imperfections, such as output resistances of MOS transistors. Techniques for frequency-domain analysis, z-domain transform calculation, time-domain analysis, and sensitivity analysis are discussed
