Introduction

Chih-Wei Wu is a prominent inventor based in Kaohsiung, Taiwan. He has made significant contributions to the fields of analog and digital technologies, holding a total of five patents. His innovative work has had a substantial impact on the development of electronic devices and systems.

Latest Patents

One of his latest patents is an analog digital converter, which includes a sample-hold circuit that samples an input voltage to generate a sample-hold output signal. This invention features a digital-to-analog converter (DAC) that generates a DAC output signal, along with a comparator that compares the DAC output signal with the sample-hold output signal to produce a comparison output signal. The design incorporates a SAR combinational digital circuit group, a multiplexer circuit, and multiple registers for registering the comparison output signal. The multiplexer circuit is controlled by the register output signals to select among the first and second SAR output signals, which are then sent to the DAC. Additionally, a capacitor coupling relationship of the DAC is controlled by the multiplexer output signals.

Another notable patent involves a method of detecting jitter in the clock of an apparatus. This invention includes a phase-locked loop and a jitter detection circuit. The method entails the phase-locked loop generating lead and lag control signals based on a reference clock and a feedback clock. The jitter detection circuit generates a jitter signal from these control signals and identifies jitters in the clock signal, ultimately outputting a jitter indication signal based on the number of jitters detected.
