A novel analog-to-residue converter for biomedical DSP application

Abstract

Digital Signal Processors (DSP) based on Residue Number System (RNS) are superior to conventional DSP especially in terms of parallel signal processing and power consumption. For modern state of the art biomedical applications, signal processing efficiency and robustness are of paramount importance. Therefore, the huge silicon overhead area and high power consumption of traditional Analog-to- Digital and Digital-to-Residue conversion scheme are not feasible to be used in the field of biomedical science. Therefore, direct Analog-to-Residue conversion begins to attract immense interest from many researchers and engineers in the world today. In this paper, a new method to realize the direct Analog-to-Residue conversion is presented. This method shows a promising characteristic for low power and process scaling via utilizing time as the intermediate method in the processing.
