This paper given a method to design and realize the low power alternative-rate outputs decimation filters.This filters included cascaded integrated comb filters
compensation filter
and half-band filter
in order to decrease its power and area consumption
this paper proposed the method which taken non-recursive and polyphase decomposition to realize the cascaded integrated comb filters
which can saved 21% power and 5% area consumption compared with Hogenaur cascaded integrated comb filters.Besides
when change the output rates
the redundant circuit can be shut down to save more power consumption.
