CASCADED INTEGRATOR-COMB (CIC) DECIMATION FILTER WITH INTEGRATION RESET TO SUPPORT A REDUCED NUMBER OF DIFFERENTIATORS

摘要

A cascaded integrator-comb (CIC) decimation filter may include N integrator stages (52), N-1 differentiator stages (56), and a decimator (54) coupled to receive an integrated signal (60) that is output from the N integrator stage (52) and generate a decimated signal (62) that is input to the N-1 differentiator stages (56). The decimator (54) may periodically assert an integration reset signal (70). A last integrator stage of the N integrator stages (52) may be reset in response to assertion of the integration reset signal (70).
