T-Gate: Concept of partial polarization in Quantum Dot Cellular Automata

Quantum Dot Cellular Automata (QCA) plays a pivotal role in the emerging field of Nano electronics as well as in digital finite state machine design arena. Several gates and their proposals exist in this field all of which are recognized for their own characteristics. Majority voter is one of the several schemes of QCA. In this paper, a new gate termed as T-gate is proposed which is validated by thirteen standard functions and two input multiplexer circuit which reflects the reduction in the effective area as compared to the realization of the same by earlier methods. The T-gate can function as a universal logic gate and also as an inverter which can be realized by using fewer numbers of cells. T-gate implementation of 2×1 Multiplexer require no wire crossings and shows noticeable reduction in the cell count.
