Latest Patents

Yizhe Hu holds a patent for a "Fractional-N frequency synthesizer based on a charge-sharing locking technique." This invention relates to a phase-locked loop (PLL) that operates using a charge-sharing locking technique, enabling both fractional-N and integer-N operation. The PLL includes a voltage pre-setting stage, an oscillator, a shared capacitive load, and a switching network. The switching network is designed to selectively connect the voltage pre-setting stage to the shared capacitive load during the pre-setting stage, applying an expected voltage to the capacitive load. Additionally, it connects the capacitive load to the oscillator during the charge-sharing locking stage to correct phase errors. The invention also incorporates frequency-tracking and waveform-learning stages to ensure robustness against process, voltage, and temperature variations, while suppressing fractional-N spurs.
