EFFICIENT DIGITAL FREQUENCY DOWN CONVERTER STRUCTURE USING CIC FILTERS AND INTERPOLATED FOURTH-ORDER POLYNOMIALS

Youngbeom Jang, Do-Han Kim, Won-Sang Lee

Abstract

In this paper, we propose an efficient digital frequency down converter (DFDC) structure using CIC (Cascaded Integrator-Comb) decimation filters and interpolated fourth-order polynomials (IFOP). Typical DFDC with high decimation factors consist of a CIC filter and a halfband filter. By inserting the proposed IFOP between the CIC and halfband filters, it is shown that passband droop and aliasing band attenuation characteristics are simultaneously improved. Since the IFOP requires only three multiplications, the proposed DFDC can be used in intermediate frequency blocks of the high-speed communication systems.
