Abstract
A switched-current elliptic decimator based on bilinear-transformed, low sensitivity ladder structure is proposed. Exactness of response and high selectivity are achieved using the bilinear-transform and elliptic structures. The decimator is implemented using polyphase input networks and a ladder structure which preserves low passband sensitivity and maximises time for settling by operating at the lower sampling frequency
