Single Electron Tunneling (SET) technology introduces more potential for feature size decrease compared to well-established silicon-based CMOS technology. The SET technology offers the ability to control the motion of individual electrons in the designed circuits. In this paper, we present a single-electron 8-3 encoder built using single-electron devices. The circuit is designed using a proper tool based on a Monte Carlo technique. The complete schematic diagrams of these basic SEC along with the corresponding simulation results (using SIMON 2.0) of these sec are included. First a single-electron OR gate is studied and then a Novel 8-3 Encoder SET, with detailed schematic and simulation results, is presented. The results proved that the circuit was an 8-3 encoder, while the behavior of the free energy of the system (which was calculated to be 4.90x10-1 eV) and the stability diagram verified the correct functioning of the circuit.
