Abstract
A duty-cycle adjustment circuit receives a differential pair of input signals and generates an output signal based on the differential pair. The duty-cycle adjustment circuit drives the output signal to a logic-high state based on transitions of a first polarity in a first input signal of the differential pair, and drives the output signal to a logic-low state based on transitions of the first polarity in a second input signal of the differential pair. For example, rising-edge transitions of the output signal may be aligned with rising-edge transitions of the first input signal, and falling-edge transitions of the output signal may be aligned with rising-edge transitions of the second input signal. Alternatively, rising-edge transitions of the output signal may be aligned with falling-edge transitions of the first input signal, and falling-edge transitions of the output signal may be aligned with falling-edge transitions of the second input signal.
