Design of a Programmable Upsampler of Broadband Data for High Speed Operation

Abstract

This paper presents the design of a high-speed programmable upsampler for the upsampling of a broadband signal. Several filter architectures and types of logic are compared. A cascaded integrator comb (CIC) filter has been selected to achieve a power efficient upsampler with a operating speed of 3 GHz with an estimated 250 mW power consumption while at the… (More)
