A driver circuit includes an output driver including a plurality of output driver legs. The driver circuit further includes a duty cycle adjuster configured to adjust a duty cycle of a signal provided to the output driver. The driver circuit further includes an isolation module configured to isolate at least one output driver leg of the output driver legs from remaining output driver legs of the output driver legs. The driver circuit further includes a duty cycle monitor configured to monitor an output of the at least one output driver leg when the at least one output driver leg is isolated from the remaining output driver legs, and to provide the monitored output to the duty cycle adjuster.
