The Single Electron Nano-Devices (SENDs) are attractive candidates for post-CMOS VLSI era mainly due to its very low power consumption. In this paper, the Linear Threshold Gate (LTG) SEND is reviewed. An Artificial Neural Network (ANN) Majority Logic Gate (MLG) with 3 inputs (MLG3) is proposed. The MLGs with three and four inputs are implemented using LTG and SET inverter SENDs. The detailed parameters for all used devices as well as the corresponding SIMON 2.0 simulation results of these MLGs are included.
