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 QCADesigner and simulation results prove its validity.
