ABSTRACT:
The present invention facilitates serial communication by performing duty cycle correction. A duty cycle correction component302performs 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 buffer306buffers the differential pair of square wave signals and provides the buffered signals to a feedback circuit304that measures duty cycles of the signals and generates the pair of adjustment signals accordingly. The buffer306can also remove skew from the signals. In a transmitter102, the buffered signals are also generally provided to a multiplexer112or encoder and in a receiver106, the buffered signals are also generally provided to a sampling component122.
