Brownian Circuits for Nanocomputers

Peper Ferdinand

Abstract

Brownian circuits are circuits that use noise and fluctuations as an active mechanism in their operation. While in traditional circuits noise is kept under control by suppressing it, such a modus operandus has become less suitable with the progress in integration densities of electronics. In circuits with nanometer-scale feature sizes it is expected that noise has such high levels that alternative methods will become necessary. This paper gives a short review of research efforts in this framework, with a focus on work by ourselves.
