Digital-to-analog converter using single-electron tunnel junctions

Abstract

We have devised a novel digital-to-analog converter (DAC) based on parallel-coupled single-electron tunnel junctions and demonstrated its functionality by performing simulation studies of a 3-bit DAC. The main features of the single-electron DAC are its ease of expansion due to its relatively simple structure and robust-to-background-charge property due to the parallel coupling of single-electron tunnel junctions.
