Zusammenfassung:Signal phase adjustment for duty cycle control is described. A first sample clock signal and a second sample clock signal are provided. A first phase signal and a second phase signal are generated responsive to the first sample clock signal, where the first phase signal is out of phase with respect to the second phase signal. The second sample clock signal configured to be swept in phase in relation to the first phase signal. A combined signal is generated where the combined signal has a duty cycle associated with the first phase signal and the second phase signal in combination. A first counter and a second counter are clocked responsive to the second sample clock signal to count. A first count from the first counter is divided by a second count from the second counter to obtain the duty cycle associated with the combined signal.
