Title: The Innovations of Ziwei Zheng

Introduction

Ziwei Zheng is an accomplished inventor based in Greensboro, NC (US). She has made significant contributions to the field of frequency synthesis and digital clock systems. With a total of 3 patents to her name, her work showcases her expertise and innovative spirit.

Latest Patents

One of her latest patents is a frequency synthesizer with dynamic phase and pulse-width control. This agile frequency synthesizer includes a count circuit that modifies a stored count value by an adjustment value. It also features an output clock generator that produces an output clock signal based on the stored count value. The count circuit can alter the period or phase of the output clock signal by modifying the adjustment rate.

Another notable patent is the digital phase-locked loop clock system. This clock system comprises a digital phase/frequency detector (DPFD), a buffer, and a digitally-controlled oscillator (DCO) that includes a sigma-delta modulator (SDM). The DPFD generates an output representing the difference between a reference input clock and a feedback signal. The buffer stores this difference signal over time, while the DCO generates an output clock signal based on the average frequency of the external clock signal.
