Abstract

A Digital Down Converter (DDC) forms an integral part of wireless receivers. The major functional blocks of a DDC constitute a mixer, Numerically Controlled Oscillator (NCO) and an FIR filter chain. In this paper, an area efficient DDC has been designed and implemented. The designed architecture achieves 44.8% area efficiency, on comparing it with that of the existing methodology. The lesser the area required, the lesser will be the power consumption, thus making it environmental friendly.
