Single-Electron devices imply the possibility to control the movement and position of a single electron or a few electrons thereby reducing the device size and power consumption. A single-electron transistor can be operated as a switch with the transition of the gate voltage between two appropriate values thereby modifying conventional logic design into the single-electron regime by simply exchanging MOSFETs with SETs. Single-electron logic circuits can thus be employed to perform arithmetic functions, thereby making single-electron technology viable to realize high density low power consumping VLSI circuits. In the present work a single electron logic based high speed power efficient 4-bit reversible binary parallel adder is designed, implemented and its performance studied on its simulated model.
