Description/Abstract

This paper describes the modeling and analysis of the non-ideal performance of the recently introduced Bruton transformations switched current (SI) wave filters. Two sources of errors are considered: mismatching in current mirrors and clock-feedthrough in delay cells. Using transistor-level realizations, analytical non-ideal models for the main components of Bruton transformations wave filters are developed including capacitive source and load, and frequency dependent negative resistors. These models are integrated with MATLAB to study the influence of these errors on the filters frequency response. The non-ideal performance of 3rd-order low-pass, and 5th-order high-pass elliptic filters using second-generation and S2I delay cells are analyzed and included.
