Abstract
The present invention provides a fractional frequency divider, wherein the fractional frequency divider includes a plurality of registers, a control signal generator and a clock gating circuit. Regarding the plurality of registers, at least a portion of the registers are set to have values. The control signal generator is configured to generate a control signal based on an input clock signal and values in the at least a portion of the registers, wherein the control generator sequentially generates the control signal during each cycle of the input clock signal. The clock gating circuit is configured to refer to the control signal to mask or not mask the input clock signal to generate an output clock signal.
