This paper presents a CMOS integrated circuit, to be used as pre-filter in video systems. The circuit is a lowpass switched capacitor decimation filter, based on the polyphase decomposition of the transfer function in structurally all pass sections. The filter presents low sensitivity to transfer function coefficient errors and low power consumption.
