A flip-flop includes a first input circuit, a first NOR logic gate, a stacked gate circuit, a first NAND logic gate and an output circuit. The first input circuit generates a first signal responsive to at least a first data signal, a first or a second clock signal. The first NOR logic gate is coupled between a first and a second node, and generates a second signal responsive to the first signal and a first reset signal. The stacked gate circuit is coupled between the first and a third node, and generates a third signal responsive to the first signal. The first NAND logic gate is coupled between the third and a fourth node, and generates a fourth signal responsive to the third signal and a second reset signal. The output circuit is coupled to the fourth node, and generates a first output signal responsive to the fourth signal.

Integrated circuit and method of forming the same

A flip-flop includes a first set of transistors of a first type being located in a first row and a second set of transistors of a second type being located in a second row. The second type being different from the first type. The first and second set of transistors include a first master latch circuit and a second master latch circuit. The first and second master latch circuit are separated from each other in the first direction by a first distance. A first output signal of the first and second master latch circuit is a first input signal of the first master latch circuit and the second master latch circuit. A second output signal of the first and second master latch circuit is a second input signal of the first and second master latch circuit.
