Supply Voltage Analysis for MRF Circuits Design based on Information Theory

Abstract

Reliability is an essential issue in circuits design. The methodology of Markova random field (MRF) provides a new way for ultra-low supply voltage design to obtain high noise-immune performance. However, MRF circuits have a lack of the analysis for the supply voltage. In this paper, we use information theory to analyze the low bound of the supply voltage. Then, we prove the MRF circuit has lower supply voltage compared to the traditional circuit under the same output correct probability. The contribution of this paper is providing a mathematical proof for MRF circuit from the information theory viewpoint in low supply voltage design.
