Abstract

See full text

The present disclosure includes circuits and methods that adjust and correct duty cycles of circuits. The circuits and methods receive a signal from a first circuit and forward the received signal to a second circuit that retrieves a first setting (X) that provides a measure of duty cycle of the received signal. The circuits and methods then invert the received signal, retrain the second circuit based upon the inverted received signal, and retrieve a second setting (Y) of the retrained second circuit. The second setting (Y) provides a measure of duty cycle of the inverted received signal. The circuits and methods then adjust the duty cycle of the received signal based upon the first and second settings (X, Y) and further retrain of the second circuit to provide an improved duty cycle in a direction closer to 50 percent.
