Project Description

The notion of exact computation, where outputs of the computational element (circuit) have precise deterministic values, as well as the fact that electronic chips are powered at nominal voltages for increased performances, have been pervasive in the computing domain for many decades owing to the overwhelming success of the integrated circuit design using reliable transistors, particularly in Complementary Metal-Oxide-Semiconductor (CMOS) technology. However, semiconductor industry is facing serious challenges today as diminishing transistor sizes driven by Moore’s law are leading to increasing process variations and additional perturbations due to temperature and voltage fluctuations which threaten the circuit functionality.
