Latest Patents
Hwang's latest patents include a self-calibrating pipelined subranging analog-to-digital converter. This innovative approach to A/D converter architecture utilizes a 'pipelined and submerged' design. It features a pipeline of elemental stages, each comprising a low-resolution flash A/D subconverter, a D/A converter, and a unity-gain buffer. To address converter nonlinearity caused by component mismatches, Hwang employs a self-calibration technique based on an interpolation scheme. This method utilizes an on-chip delta-sigma A/D converter to provide calibration references and a memory to store nonlinearity information. Additionally, long-term drift is corrected by a calibrator operating in parallel with data conversion.
Another significant patent is a pipelined analog-to-digital architecture with parallel-autozero analog processing. This architecture consists of three pipeline stages, with the first stage incorporating a low-resolution flash A/D subconverter, two sample-and-hold amplifiers, two D/A converters, and two unity-gain buffers. The design allows for high-speed operation while maintaining accuracy, as the first stage D/A converters provide good precision.
