Title: The Innovative Contributions of Nick Tu
Introduction
Nick Tu is a prominent inventor based in Alhambra, CA, known for his significant contributions to semiconductor imaging technology. With a total of 2 patents, Tu has developed innovative solutions that enhance the performance and reliability of imaging devices.
Latest Patents
Tu's latest patents include a "System, method, and apparatus for correction of dark current error in semiconductor imaging devices." This invention features detection cells designed to output signals for dark current error correction. Various embodiments of these detection cells accumulate dark charge supplied by dark current sources and output dark charge signals that indicate the amount of accumulated dark charge. These signals can be utilized to approximate the dark charge read out by pixel cells of an imaging array and offset portions of pixel cell signals attributable to dark charge accumulation.
Another notable patent is the "Amplifier shared between two columns in CMOS sensor." This invention provides improved shared amplifier circuitry and a method of operation that minimizes offset and column-to-column fixed pattern noise during readout operations. The circuit enhances the consistency of pixel-to-pixel output in the pixel array, increases the dynamic range of pixel output, and conserves chip area. This is achieved by simultaneously sampling and storing charge accumulated signals from two desired pixels in respective columns, amplifying the signals, and outputting the results efficiently.
