ABSTRACT

This paper extends the class of sharpened modified comb filter(SMCF) introduced by Missimilano Laddomada for ∑∆ A/D converters in order to obtain more improved response i.e., lesser pass band droop than SMCF and alias rejection better than basic CIC with the use of compensation techniques along with SMCFs. Sine based compensation and the maximally flat compensation are applied to SMCF by Laddomada for achieving improved results. The overall response improvement is targeted in this paper. Zero droop in pass band and better alias rejection is achieved for SMCFs which is shown with the help of computer simulations.
