ALEXANDRIA, Va., April 15 -- United States Patent no. 12,603,658, issued on April 14, was assigned to ROHM Co. LTD. (Kyoto, Japan).
"Successive approximation register A/D converter" was invented by Haruaki Nakamura (Kyoto, Japan).
According to the abstract* released by the U.S. Patent & Trademark Office: "A capacitive array D/A converter samples an input voltage, and outputs a signal that corresponds to the input voltage IN and a threshold voltage based on control data. A comparison circuit receives an output of the capacitive D/A converter and performs comparison processing according to a comparison clock. A clock generating circuit generates a successive approximation clock. A logic circuit supplies the comparison clock to the compariso...
