Abstract

A single-electron (SE) device based on “collision-based computing (CBC)” is proposed for information processing. CBC is an analog computing in which input signals behave like billiard balls, and the goals of moving balls are regarded as output positions. The proposed SE device consists of arrayed SE oscillators with coupling capacitor between each pair. An SE oscillator is a threshold decision device which can be used as a reaction-diffusion (RD) model, a kind of the analog computation model. The RD model can express the various behaviors of an excited wave, e.g., “moving at a constant velocity” and “disappearing due to collision”. These behaviors are also important for CBC. We designed basic SE-CBC circuits and a full adder as an application, and evaluated their operation by Monte-Carlo computer simulation. The results indicate that this circuit is useful for configuring various types of logical circuits.
