A new architecture for T flip flop using quantum-dot cellular automata

QCA is a novel technology which provides implementation of digital circuits in nanoscale. QCA circuits work in higher speed, smaller size and less power consumption compared to conventional CMOS circuits. In this paper, a new design for T flip flop (T-FF), by using of special feature of QCA circuits capabilities, is proposed. This T-FF has additional inputs that can be used better in sequential circuits as memory elements. These inputs can reset and preset T-FF and no more cells needed to add them to the designed circuit. Proposed T-FF is simulated using the QCA Designer and simulation results prove its validity.
