Latest Patents

One of Guo's latest patents is a "Duty cycle correction circuit for high-speed clock signals." This invention implements an apparatus designed to correct duty cycle distortion in high-speed clock signals. The apparatus includes delay cells that delay each of the first and second differential initial clock signals. Additionally, it features a latch that generates an output clock signal based on the delayed signals, along with a differential feedback buffer that converts the output clock signal into first and second differential feedback signals. A feedback circuit adjusts the delay cells based on these feedback signals, enhancing the performance of high-speed clock systems.

Another significant patent is the "Multiple frequency generator for quadrature amplitude modulated communications." This invention provides multiple carrier frequencies from a phase-locked loop, particularly for closely adjacent quadrature amplitude modulated subcarriers used in multiplexed data communications. The system employs a quadrature voltage-controlled oscillator (VCO) and cascaded frequency dividers to lock the VCO to a reference signal. The technique efficiently generates sequential integer multiples of a basic frequency, which is crucial for modern communication systems.
