Application of Single Electron Threshold Logic based Device: - A case study

The very high density of integration and ultra-low power consumption characteristics has given the Single electron devices promising capabilities to replace CMOS transistors in some applications. There are also alternative logic design styles, such as threshold logic, that may be more suitable and also more powerful for novel technologies such as single electron technology. In this paper, we investigate single electron threshold logic gate implementation of some logic circuits, in which the Boolean logic values are encoded as absence or presence of one electron. We present a control unit for a chemical process. Computer based realization of the control unit is performed using SIMON simulation tool. The performance of the simulated model is studied with some sample data and found satisfactory thereby establishing the feasibility of using single electron threshold logic based devices for high future high density low power VLSI/ULSI circuits.
