Publication number: 20240028057Abstract: A method and apparatus for performing dynamic current scaling of an input current of a voltage regulator are provided. The method and apparatus allow tuning current consumption in various applications, calculating a duration of an activity phase in which various algorithms are executed and activating dynamic current scaling of a regulator if the activity duration is shorter than a programmable threshold. A controller receives a threshold for an activity duration and a window size in which to evaluate the activity duration.Type: ApplicationFiled: September 27, 2023Publication date: January 25, 2024Applicant: STMICROELECTRONICS S.r.l.Inventors: Carmela MARCHESE, Rossella BASSOLI

Publication number: 20230370524Abstract: The present disclosure is directed to a device and method for generating and transmitting a TDM signal including both raw data and processed data. The device includes a sensor having a time division multiplexing (TDM) interface. The TDM interface transmits both raw data and processed data in a single TDM signal by reserving one or more slots inside a TDM frame for transmission of the processed data. The sensor also embeds additional information inside a data stream of raw data by repurposing one or more of values of the raw data as an exception code, flag, or another type of notification. The device is also enabled to transmit data, and disabled when not in use in order to conserve power.Type: ApplicationFiled: July 27, 2023Publication date: November 16, 2023Applicant: STMICROELECTRONICS S.r.l.Inventors: Alessandra Maria RIZZO PIAZZA RONCORONI, Matteo QUARTIROLI, Rossella BASSOLI, Paola BALDRIGHI

Patent number: 10379173Abstract: A magnetic field sensor generates signal components corresponding to an uncalibrated representation of a sensed magnetic field in a three-dimensional coordinate system. A reader coupled to the magnetic field sensor determines a center offset based on received signal components, adjusts the received signal components based on the determined center offset, and applies Kalman filtering to the adjusted signal components, generating a set of ellipsoid parameters. The reader generates calibrated signal components based on the determined center offset and the generated set of ellipsoid parameters.Type: GrantFiled: March 21, 2016Date of Patent: August 13, 2019Assignee: STMICROELECTRONICS S.R.L.Inventors: Rossella Bassoli, Carlo Crippa
