Abstract :
This paper presents an efficient design of low-complexity wide-band compensators to improve the passband characteristic of Cascaded Integrator Comb (CIC) filters. The proposed compensators are designed using the amplitude transformation method recently presented in a companion paper. This work also provides a simple formula to obtain the coefficients of the compensator. Design examples and comparisons were addressed to show that the proposed compensation filters have better frequency characteristics compared to other wide-band compensators recently presented in the literature.
