Title: Jhy-Rong Chen: Innovator in Sigma-Delta Modulation Technology

Introduction

Jhy-Rong Chen is a notable inventor based in Tainan, Taiwan. He has made significant contributions to the field of sigma-delta modulation technology, holding a total of 2 patents. His work focuses on enhancing the performance and stability of high-order sigma-delta modulators.

Latest Patents

One of his latest patents is a "Stabilizing mechanism for sigma-delta modulator." This invention introduces a technique known as 'Internal Linear Feedback (ILF)' for stabilizing high-order sigma-delta modulators. The ILF technique utilizes an overload detector and a selector. When an overload is detected, the selector activates the modulator to enter ILF mode, employing additional internal linear feedback paths to stabilize the modulator. In normal conditions, the modulator operates as a general high-order modulator.

Another significant patent is the "4th-order sigma-delta modulator with leapfrog topology." This invention features a high-performance and absolutely stable 4th-order sigma-delta modulator. Key components include four integrators for integrating the difference signal, three add/subtract adders for manipulating the analog signal, and three loop coefficient control members for managing performance and stability. Additionally, it incorporates an analog-to-digital converter (A/D converter) for quantizing output signals and a digital-to-analog converter (D/A converter) for converting digital codes back to analog signals.
