Title: The Innovations of Ping-Chuan Chiang

Introduction

Ping-Chuan Chiang is a notable inventor based in Yilan, Taiwan. He has made significant contributions to the field of high-speed data serialization, holding a total of 4 patents. His work focuses on enhancing data transmission efficiency and accuracy through innovative clock calibration techniques.

Latest Patents

One of his latest patents is the "Clock phase aligner for high speed data serializers." This invention relates to a high-speed data serializer equipped with a clock calibration module. The module includes a main multiplexer (MMUX), a replicated multiplexer (RMUX), a duty cycle calibration module (DCC), and a set of adjustable delay lines (ADLs). The ADLs generate calibrated clocks from a set of system clocks, while the DCC senses the duty cycle and phase of these calibrated clocks. The DCC can generate error signals that indicate deviations from the expected duty cycle, which are then used to control the ADLs for continuous clock corrections. The MMUX and RMUX utilize these calibrated clocks to enhance data multiplexing and reduce jitter, thereby facilitating increased data rates for high-speed serial data streams.

Another significant patent is the "Quadrature clock correction circuit for transmitters." This circuit features a first pair of clock correction circuits that output in-phase and anti-in-phase clock signals from a four-phase clock signal. Additionally, it includes a second pair of clock correction circuits that output quadrature-phase and anti-quadrature-phase clock signals. A detector circuit is designed to identify duty cycle errors and phase mismatches in the four-phase clock signal. The calibration circuit then supplies control signals to correct these errors, ensuring optimal performance in data transmission.
