Abstract
In one aspect, a duty cycle controller includes a first port configured to receive a voltage bias signal, a second port configured to receive an input voltage signal, a third port configured to provide an output signal of the duty cycle controller having a duty cycle and a n-bit digital-to-analog converter (DAC) configured to receive the voltage bias signal and to provide a DAC output signal to a comparator. The DAC output signal has a peak value. The duty cycle controller also includes the comparator configured to compare the DAC output signal from the n-bit DAC with the input voltage signal to provide a comparator output signal. The comparator output signal is used to provide the output signal of the duty cycle controller and the duty cycle changes with changes to the input voltage signal.
