Abstract
Down Converter (DDC), which is basically used to convert an intermediate frequency (IF) signal to its baseband form, 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 and high speed DDC has been designed and implemented. On comparison of the results with that of the existing methodology, the designed architecture achieves 44.8% area efficiency and 80.7% improvement in speed.
