Latest Patents

Tze Haw Liew holds a patent for a "Clock duty cycle recovery circuit." This invention encompasses circuits, methods, and apparatus designed to improve or recover the duty cycle of a clock signal. One embodiment of this invention receives a clock signal that may have a degraded duty cycle. The frequency of the clock signal is divided by two, and the frequency-divided signal is delayed to generate two signals that are phase-shifted from one another by 90 degrees. These signals are then exclusive-ORed together to produce a recovered clock. A control loop is incorporated to adjust the phase shift between the signals to be approximately 90 degrees. This innovative approach enhances the reliability of clock signals in various electronic applications.
