Abstract
The present invention facilitates serial communication by performing duty cycle correction. A duty cycle correction componentperforms duty cycle corrections on a pair of differential sinusoidal signals according to a pair of adjustment signals and, as a result, generates a differential pair of square wave signals. A cross coupled bufferbuffers the differential pair of square wave signals and provides the buffered signals to a feedback circuitthat measures duty cycles of the signals and generates the pair of adjustment signals accordingly. The buffercan also remove skew from the signals. In a transmitter, the buffered signals are also generally provided to a multiplexeror encoder and in a receiver, the buffered signals are also generally provided to a sampling component
