Title: Minjie Wu: A Pioneer in Voltage Controlled Oscillator Technologies
Introduction
Minjie Wu is a notable inventor based in Singapore, renowned for his contributions to the field of integrated circuits and high-speed detection modules. With two registered patents, he has made significant advancements that enhance the performance and efficiency of electronic devices.
Latest Patents
One of Minjie Wu's latest patents is for a **Voltage Controlled Oscillator**. This integrated circuit features a comprehensive design that includes a bias circuit, an LC resonator circuit, and a current mode logic (CML) frequency divider. The bias circuit is responsible for generating the first and second bias voltages, while the LC resonator circuit produces an oscillation signal with a specific oscillation frequency. The CML frequency divider takes the oscillation signal—comprised of both AC and DC components—and generates an output signal at a frequency that is a fractional rate of the oscillation frequency. By utilizing the AC component to determine an injected frequency and the DC component to establish tail currents, the CML divider optimizes its natural frequency, thus enhancing overall circuit performance.
In addition, Wu has developed a **High-Speed Phase-Frequency Detection Module** designed to operate at very high frequencies with minimal jitter. This patent describes a PFD that employs edge-triggered asynchronous-reset true-single-phase-clocking (TSPC) D flip-flops known for their exceptionally short CLK to Q and Reset to Q time delays. This module includes a charge pump that effectively responds to narrow pulses from the PFD, resulting in output voltages characterized by low ripple and, consequently, reduced VCO output jitter.
