Abstract
This paper presents a double sharpened CIC decimation filter, which consists of generalized comb filter as first stage, sharpened comb filter as second and third stage. The comb decimation filter at the first stage operates at the input sampling rate, sharpened second stage operates at lower sampling rate as compared to first stage and sharpened third stage operates at lower than the first and second stages. This reduces the sampling at every stage of the three stage CIC decimation filter. The sharpened second stage produces the narrow passband droop and better stop band alias rejection. This narrow passband droop will be compensated with the help of third stage which is sharpened section. This filter structure is designed in MATLAB Simulink environment and implemented with help of Virtex-V XC5VLX110T-3ff1136. Device utilization and simulation results are tabulated.
