Abstract
Aspects of the disclosure provide a clock gate circuit for generating a clock signal. The clock gate circuit includes a multiplexer and a logic module coupled to the multiplexer. The multiplexer is configured to receive a first logic signal at a first data input, a second logic signal at a second data input, and a reference clock signal at a selector input, and to output the clock signal having a logic state selected from one of the first logic signal or the second logic signal based on transitions of the reference clock signal. The logic module includes at least one of an XNOR and an XOR module and is configured to provide an output signal that is responsive to performing at least one of an XNOR and an XOR operation of the output of the multiplexer and an enable signal that enables or disables the clock gate circuit to generate the clock signal.
