Direct residue-to-analog conversion scheme based on Chinese Remainder Theorem

Residue Number System (RNS) allows parallel digital signal processing due to the absence of carry propagation between its arithmetic units. The RNS implementation results in great performance in terms of speed and power, especially when recursive multiply-and-accumulate operations are required. In this paper, we propose a direct residue-to-analog conversion architecture. The proposed architecture, based on the Chinese Remainder Theorem, eliminates the need of conversion to binary encoding as an intermediate stage. The proposed converter is useful for direct interaction of residual arithmetic-based signal processing with the analog world.
