A T flip-flop, which is an essential element of a counter, has been proposed as various types of quantum-dot cellular automata (QCA) circuits, but practicality is not expected because there is no clock in circuit. A T flip-flop is a circuit which outputs value changing in synchronization with the rising or falling edge of a clock. In a QCA circuit, a clock pulse generator outputs the time at which the clock changes and it is required for the circuit. In this paper, we propose a falling-edge triggered T flip-flop based on QCA.
