Title: Innovations of Hongfei Wu

Introduction

Hongfei Wu is a notable inventor based in Colchester, Vermont, USA. He has made significant contributions to the field of digital clock generation and programmable delay units. With a total of 6 patents to his name, his work has had a considerable impact on electronic circuit design.

Latest Patents

One of his latest patents is for a digital clock generation circuit. This circuit includes a first, second, and third differential comparator circuit. The first differential comparator circuit receives the positive differential clock signal and a reference voltage, generating a first output signal. The second differential comparator circuit processes both positive and negative differential clock signals to produce a second output signal. The third differential comparator circuit utilizes the reference voltage and the negative differential clock signal to generate a third output signal. A high-high detecting circuit then receives the first and third output signals to generate an Enable signal. The circuit also features a latch circuit that receives the second output signal and the Enable signal, producing a digital clock signal with glitch or noise immunity.

Another significant patent is for a dual edge programmable delay unit. This invention includes a buffer that responds to an input signal with both rise and fall times. The buffer provides an output signal with programmed variable delays between these rise and fall times. Programmable control sources offer separate control inputs to the buffer, allowing for precise adjustments to the timing of the output signal.
