Efficient wide-band droop compensation for CIC filters: ad hoc and reconfigurable FIR architectures

Novel finite impulse response architectures for wide passband droop compensation of cascaded integrator-comb filters are presented. Compared with the recent wide-band compensators introduced in the literature, the proposed systems achieve better passband droop correction with lower power dissipation, lower hardware utilisation and higher maximum frequency of operation, as validated with post-place-and-route information from FPGA-based implementations.
