摘要:
Circuits and a method for correcting duty cycle distortions in an integrated circuit (IC) are disclosed. The IC includes a splitter circuit that is coupled to receive a clock signal. The clock signal is split into two different clock signals. One of the clock signals is an inverted version of the other. A delay circuit is coupled to each of the clock signals. Each of the delay circuits generates a delayed version of the corresponding clock signal. A corrector circuit is coupled to receive both the delayed versions of the clock signals. The corrector circuit generates a clock output signal with a corrected duty cycle.
