Abstract
A duty cycle correction system corrects for duty cycle distortion by measuring average time interval durations of consecutive intervals of an input signal. The system generates complementary ramp signals that have cross-points indicating midpoints of the intervals, and detects those cross-points. An output circuit of the duty cycle correction system generates an output signal that performs rising and falling transitions in response to the detected cross-points.
