Introduction

Yuan-Kai Chu is a notable inventor based in Tainan County, Taiwan. He has made significant contributions to the field of electronics, particularly in the development of analog-to-digital converters and current-mode differential transmitters. With a total of seven patents to his name, his work has had a considerable impact on modern technology.

Latest Patents

One of his latest patents is the "Successive Approximation Analog to Digital Converter," commonly referred to as a SAR ADC. This invention is designed to convert an analog input into an N-bit digital output during a conversion phase. It includes three comparators and two capacitor sub-arrays coupled to each comparator. The capacitor sub-arrays are utilized for sampling the analog input and providing inputs for the corresponding comparator. The SAR logic is responsible for coupling selected capacitors to reference levels and generating the digital output based on the data from the comparators.

Another significant patent is the "Current-Mode Differential Transmitter and Receiver." This invention involves a current-mode differential transmitter that receives a single-end input voltage signal and generates a differential output current signal. The transmitter comprises a first switch, a second switch, and a current mirror. The first switch is controlled by the input voltage signal, while the second switch is controlled by an inverted version of that signal. The current mirror plays a crucial role in mirroring a reference current to the appropriate current path, thus deriving the differential output current signal.
