Advocating Noise as an Agent for Ultra-Low Energy Computing: Probabilistic Complementary Metal-Oxide-Semiconductor Devices and Their Characteristics

摘要: Noise immunity and low-energy computing have become limiting factors in the semiconductor roadmap as transistor feature sizes shrink. The subject of our study is probabilistic switch, implemented complementary metal–oxide–semiconductor (CMOS) domain, referred to a CMOS (PCMOS) whose behavior rendered by noise. In conducting this study, we are motivated possibility using such switches realize ultra-low energy computing. Based on PCMOS realized 0.5 0.25 µm processes, present detailed analytical models, subsequently verified through HSpice simulations. We consider thermal noise power supply sources for behavior. Through one interesting aspect characterize effects sampling frequency output Finally, briefly outline opportunity that offer ultra concept system-on-a-chip (PSoC) architecture (that based switches); architectures can achieve significant savings performance improvements at application level.
