A divider circuit determines whether an input factor (N) is an even number or an odd number. If N is an even number then the input clock is divided by N/2 to generate an intermediate clock. The intermediate clock is further divided by two to generate a div-by-2 clock, which is provided as the output clock with fifty percent duty cycle. If N is an odd number, the input clock is divided by (N/2−0.5) in a first duration and by (N/2+0.5) in a second duration to generate the intermediate clock, which is then divided by two to generate the div-by-2 clock. A delayed clock is generated from the div-by-2 clock, wherein the delayed clock lags the div-by-2 clock by half cycle duration of the input clock. The div-by-2 clock and the delayed clock are combined to generate the output clock with fifty percent duty cycle.
