Title: Innovations of John Oh in Signal Edge Detection
Introduction
John Oh is a notable inventor based in San Jose, CA, who has made significant contributions to the field of signal processing. He holds a total of 3 patents, showcasing his expertise and innovative spirit in developing advanced technologies.
Latest Patents
One of John Oh's latest patents focuses on signal edge detection circuitry and methods. This invention enhances double data rate (DDR) circuitry by incorporating edge detection capabilities. During the edge detection mode, the circuitry receives serial training data that consists of successive pairs of equal-valued bits. The process involves using several differently-phased candidate clock signals sequentially to clock the DDR circuitry. The adjacent bits in the training data, which are expected to be equal-valued, are captured and compared by the DDR circuitry. Any candidate clock signal that results in unequal bits is flagged, indicating that its phase is close to the edges in the data. Consequently, the approximate phase of data edges is determined by the phases of the candidate clock signals that cause the bits to be unequal.
