Digital to analog conversion performed in single electron technology

Abstract

Investigates SET devices from the logic design perspective, using the SET tunnel junction's ability to control the transport of individual electrons. We introduce a modified turnstile circuit with clock and enable control signals, which has built-in memory and reset functionality. Using the modified turnstile circuit as a building block, we propose a scheme for an n-input digital to analog converter. We demonstrate the scheme by implementing and simulating a 3-bit digital to analog converter.
