ALEXANDRIA, Va., Feb. 11 -- United States Patent no. 12,549,162, issued on Feb. 10, was assigned to STMicroelectronics International N.V. (Geneva).
"Voltage ramp generator" was invented by Abdessamed Mekki (Isere, France) and Laurent Simony (Grenoble, France).
According to the abstract* released by the U.S. Patent & Trademark Office: "A circuit includes a first capacitance array formed by n nominally equal capacitive elements. A first electrode of each capacitive element is coupled, via respective switches to either a reference voltage or ground. A differential amplifier has a first input coupled to an output of a first capacitance array, a second input grounded, and an output generating a voltage ramp. A capacitive feedback circuit coupl...
