He holds 2 patents that showcase his expertise in developing advanced technologies for phase locked loop (PLL) systems. His work has significantly impacted the field of electronics and signal processing.
Latest Patents
One of Xiaobo Qiu's latest patents is a digitally controlled oscillator (DCO) for a phase locked loop (PLL) system. This invention includes a plurality of selectable delay cells, a first load adjustment delay (LAD) cell, a second LAD cell, and various load cells. The DCO is designed to generate a delay cell output signal that is configurable based on a delay cell number control vector. This innovation allows for precise control over loading in the DCO by adjusting substrate voltages of capacitance elements.
Another significant patent is a digital phase locked loop (PLL) system and method with phase tracing. This control system implements a phase tracer module to reduce lock time and output clock jitter. It generates a second clock signal by dividing a reference clock signal's frequency and produces a feedback clock signal based on a high-frequency clock from the DCO. The phase tracer module processes lead/lag detection results to generate a digital control signal that adjusts the cycle time of the DCO, enhancing the frequency of the high-frequency clock signal.
