Methods and circuits for correcting a duty-cycle of a signal by delaying the signal and generating an output signal responsive to state transitions of the signal and the delayed version of the signal

摘要

A signal is duty-cycle corrected by delaying the signal to generate a delayed version of the signal and generating an output signal that transitions from a first state to a second state responsive to a transition of the signal from the first state to the second state and a transition of the delayed version of the signal from the second state to the first state. The output signal transitions from the second state to the first state responsive to a transition of the signal from the second state to the first state and a transition of the delayed version of the signal from the first state to the second state.
