Abstract: This paper proposes an analog-digital converter (ADC) using Single-electron transistor (SET). Single Electron Transistor is Nanodevice having a small quantum dot or island instead of the channel that works on the principle of Coulomb blockade which allows one electron tunnelingat a time from source to drain terminal. SET operates at low voltage and consumes lesspower. The proposed Flash ADC consists of SET based priority encoder and comparator circuits. The proposed design offers large input/output voltage swing, ultra-low power, compact circuit block for ADC compared to SET/CMOS hybrid amplifier-based ADC. In this paper, we have designed a 4-bit and 8bitFlash ADC using SET operating at room temperature and the performance estimationwas performed by using the CADENCE VIRTUOSO simulator.
