Abstract: As a new current-mode technique, switched current has been in a forward position of current-mode analog signal processing. This paper submitted a signal-flaw graph analysing method for switched current networks by introducing concepts of odd mirror and even mirror, and applied them to analyse the switched current filter. The result of computer simulation verified the reliability and feasibility of the method. -
