Title: Innovations of Tzi-Hsiung Shu
Introduction
Tzi-Hsiung Shu is a notable inventor based in Melbourne, FL, who has made significant contributions to the field of electronics. He holds a total of 4 patents, showcasing his expertise and innovative spirit in developing advanced technologies.
Latest Patents
One of his latest patents is a processor-controlled analog-to-digital converter circuit. This circuit includes an analog-to-digital converter (ADC) and one or more switched capacitor amplifier stages connected in series. The first stage receives the analog input signal, while the last stage connects to the ADC. Each switched capacitor amplifier stage has a selectable gain, allowing for control of the overall gain of the analog input signal before it reaches the ADC. Additionally, the first stage can function as a sample and hold circuit for the ADC. The design may incorporate an integrated circuit substrate, making the analog-to-digital converter a monolithic integrated circuit. The circuit also features a digital gain control word that adjusts the gain of the amplifier stages, with a clock connected to the ADC and amplifier stages for rapid gain changes.
Another significant patent involves a method and apparatus for calibrating integrated circuits. This calibration method includes driving the ADC with a test signal and performing a series of successive ADC calibrations. It generates a series of figure of merit measurements that define a curve with a local minimum or maximum. The calibration process stops at the point corresponding to this local minimum or maximum. The method also involves fitting an equation to the figure of merit measurements to determine the local minimum or maximum, which may include fitting a polynomial equation.
