Abstract

The invention relates to a circuit for performing logical operations and a flip-flop including the same. In the present disclosure, an integrated circuit includes a first circuit, a second circuit, and an inverter. The first circuit receives a first input signal, an inverted clock signal, a first logic level of a first output node and a logic level of a second output node to determine a second logic level of the first output node. The second circuit receives the first input signal, the clock signal, the first logic level and the second logic level to determine the logic level of the second output node. The inverter receives a second input signal to output the inverted second input signal to the first circuit or the second circuit. When the logic level of the clock signal is the first logic level, the logic level of the first output node or the logic level of the second output node is output as an output signal.

Description

technical field [0001] The inventive concept relates to circuits for performing logic operations, and more particularly, to flip-flops including the same. Background technique [0002] An integrated circuit (IC) is a set of electronic circuits disposed on a semiconductor material. An integrated circuit may include a number of active devices (eg, transistors and diodes) and passive devices (eg, capacitors and resistors). [0003] An integrated circuit may include multiple sequential circuits formed from active and passive devices. A sequential circuit may refer to a circuit that outputs output data based on input data and previously stored data. The sequential circuit may include, for example, a latch, a flip-flop (FF) or an integrated clock gating (IGC) unit. Outputs from sequential circuits may be input to combinational logic circuits for performing functions, and outputs from combinational logic circuits may be input to other sequential circuits. [0004] As ICs become...
