Title: Innovations by Degang James Chen
Introduction
Degang James Chen is a prominent inventor based in Ames, IA (US). He has made significant contributions to the field of temperature sensing and voltage reference generation. With a total of 9 patents to his name, Chen's work is characterized by innovative solutions that address critical challenges in various applications.
Latest Patents
One of Chen's latest patents is a "Wide range temperature-to-digital converter without explicit data converters." This invention relates to a temperature-to-digital converter designed for applications such as automotive, where sensing temperature across a wide range is essential. Traditional temperature sensors often have limitations due to their dependency on transistor models. Chen's design overcomes these limitations by introducing a sensor that operates independently of the transistor model, effectively cancelling and matching temperature non-linearity across different blocks. This innovative approach allows for temperature sensing in an unprecedented range of −55° C. to 200° C.
Another notable patent is the "Voltage reference generator with linear and non-linear temperature dependency elimination." This invention presents a voltage reference generator that operates without temperature dependency. It includes a precursor voltage generator and a voltage extractor, which work together to provide an output voltage that is independent of temperature variations. By scaling and summing various voltage components, Chen's design effectively eliminates both linear and nonlinear temperature-dependent components, resulting in a stable output voltage.
