Publication number: 20240036595Abstract: A low-drop out voltage regulator includes a pass element arranged between an input terminal and an output terminal, a feedback network configured to produce a feedback voltage derived from an output voltage, and an error amplifier configured to drive the pass element as a function of a difference between the feedback voltage and a reference voltage. An output transistor coupled in series with the pass element is controlled by a mode selection circuit. In response to assertion of a mode selection signal, the mode selection circuit turns on the output transistor to sink a current with a controlled magnitude from the output node. In response to de-assertion of the mode selection signal, the mode selection circuit sinks a current with a controlled magnitude from a control terminal of the output transistor to turn off the output transistor at a controlled rate.Type: ApplicationFiled: July 21, 2023Publication date: February 1, 2024Applicant: STMicroelectronics S.r.l.Inventors: Umberto FERLITO, Michele VAIANA, Giuseppe BRUNO, Alfio Dario GRASSO

Publication number: 20230236161Abstract: A gas sensor is formed by a thin-film semiconductor metal-oxide gas sensing layer, with a thermally conductive and electrically-insulating layer in direct physical contact with a back of the gas sensing layer to carry the gas sensing layer. Sensing circuitry applies a voltage to the gas sensing layer and measures a current flowing through the gas sensing layer. The current flowing through the gas sensing layer is indicative of whether a gas under detection has been detected by the gas sensing layer, and serves to self-heat the gas sensing layer. A support structure extends from a substrate to make direct physical contact with and carry the thermally conductive and electrically insulating layer about a perimeter of a back face thereof, with the support structure shaped to form an air gap between the back of the thermally conductive and electrically insulating layer and a front of the substrate.Type: ApplicationFiled: December 30, 2022Publication date: July 27, 2023Applicants: STMicroelectronics PTE LTD, STMicroelectronics S.r.l.Inventors: Ravi SHANKAR, Wei Ren Douglas LEE, Giuseppe BRUNO
