Abstract
A frequency divider circuit includes a counter configured to generate a counter signal responsive to a frequency of a clock signal and a frequency ratio, and a compensation circuit coupled to the counter, and configured to generate an output signal. The output signal has a frequency equal to the frequency of the clock signal divided by a frequency ratio, and a duty cycle greater than 1/r, where r is the frequency ratio.
