摘要：

The paper describes the modelling and analysis of the non-ideal performance of recently introduced Bruton transformation switched current (SI) wave filters. Two sources of errors are considered: mismatching in current mirrors and clock-feedthrough in delay cells. Using transistor-level realisations, analytical non-ideal models for the main components of Bruton transformation 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 filter frequency response. The non-ideal performance of 3rd-order low-pass and 5th-order high-pass elliptic filters using second-generation and (SI)-I-2 delay cells are analysed and included.
