Title: Innovations of Chien-Hui Tsai

Introduction

Chien-Hui Tsai is a notable inventor based in Hsinchu, Taiwan. He has made significant contributions to the field of electronics, particularly in the development of innovative circuits and systems. With a total of 5 patents to his name, Tsai continues to push the boundaries of technology.

Latest Patents

One of his latest inventions is a level shifter, which can achieve a level shift by a wide margin. This level shifter includes a latch circuit, a protection circuit, and an input circuit. The latch circuit is coupled between a high-voltage terminal and the protection circuit. The protection circuit, which includes a first protection transistor pair and a second protection transistor pair, is set between the latch circuit and the input circuit. It is configured to prevent an excessive voltage drop between the input circuit and a pair of output terminals, which are used for outputting a pair of output signals. The input circuit consists of an input transistor pair coupled between the second protection transistor pair and a low-voltage terminal, operating according to a pair of input signals.

Another significant patent is related to the output stage of an Ethernet transmitter. This output stage is coupled to a resistor and includes a first output terminal, a second output terminal, a first transistor, and a first transistor group. The resistor is positioned between the first output terminal and the second output terminal. The first transistor has a first source, a first drain, and a first gate, with the first source coupled to a first reference voltage and the first drain connected to the second output terminal. The first transistor group, which includes multiple transistors connected in parallel, is also coupled to the first reference voltage and the first output terminal. The magnitude of the current flowing to the first output terminal is related to the number of transistors that are turned on.
