Abstract
An electronic system according to various aspects of the present invention comprises a signal generator configured to generate a first signal and a duty cycle correction circuit configured to be responsive to the first signal and provide a corrected signal having a corrected duty cycle. The duty cycle correction circuit may include a duty cycle detection circuit and a signal adjustment circuit. The duty cycle detection circuit is suitably configured to identify a disparity between a corrected duty cycle of the corrected signal and a target duty cycle. In one embodiment, the duty cycle detection circuit includes a self-bias circuit configured to generate a control signal according to the disparity between the corrected duty cycle and the target duty cycle. The signal adjustment circuit may be responsive to the control signal and configured to provide the corrected signal having the corrected duty cycle according to the control signal.
