Voltage Controlled Reconfigurable Logic Computation in Single Electron Encoded Logics

The reconfigurable logic gates and adder-subtractor units using linear threshold gate have been proposed based on single electron box. In the proposed work, voltage control for reconfiguration has been used for realizing the reconfigurable logic structure in non inverting approach without buffer. The concept of electron encoded logic realizes the logic behaviour by controlling the gate threshold to the desired value. The voltage controlled electron encoded logic exploits the importance of the bias voltage to be the effective control for threshold gate adjustment; it enhances the feature of flexibility and re-configurability and does not require external buffers. In the proposed approach the maximum weightage is given to the bias voltage, this enables single and adequate control to realize various functions that enable the reconfigurable nature. This paper explains the design of voltage controlled Single electron encoded logic based reconfigurable logic gates and full adder/subtractor architecture. The performances are verified by simulation and also analyzed in terms of area, gate delay and energy consumption.
