Publication number: 20260098892Abstract: An electronic circuit includes a first circuit to be tested and a second circuit coupled to the first circuit and having at least components similar to those of the first circuit. The electronic circuit operates to: adopt a first state in which a determination of at least one indicator of aging of the first circuit is performed by measuring a value of the indicator using the second circuit, and then adopt a second state in which the first circuit is subjected to operating conditions causing aging, and then adopt the first state again. A comparison is then made of the determined values of the at least one indicator. The operation of the electronic circuit is then adapted according to the result of the comparison.Type: ApplicationFiled: October 7, 2025Publication date: April 9, 2026Applicant: STMicroelectronics International N.V.Inventors: Bruno LEDUC, Sebastien DEDIEU, Jimmy FORT

Publication number: 20250105999Abstract: A device of contactless communication by active load modulation includes a receive circuit configured to receive as an input a reception signal originating from a magnetic field intended to be received by an antenna. A transmit circuit has an output coupled to the antenna with a modulation signal in phase with the reception signal intended to be delivered thereon. A circuit compensates for a delay of the modulation signal due to the transmit circuit and to the amplitude of the reception signal. The compensation circuit determines a phase-shift value to be applied to an input signal of the transmit circuit to compensate for the delay.Type: ApplicationFiled: September 16, 2024Publication date: March 27, 2025Applicant: STMicroelectronics International N.V.Inventors: Marc HOUDEBINE, Bruno LEDUC, Florent SIBILLE

Patent number: 11444591Abstract: A method for controlling a signal envelope shape of modulation pulses in a driver of a wireless transmitter includes supplying a first voltage to the driver during a non-modulated state, supplying a second voltage configurable by a configurable modulation index value to the driver during a modulated state, switching between the non-modulated state and the modulated state comprising setting the modulation index value to configure the second voltage level at the same level as the first voltage and then switching between supplying the first voltage to the driver and supplying the second voltage to the driver, and filtering to a limited bandwidth the variations of the second voltage resulting from configuring the modulation index value.Type: GrantFiled: June 29, 2020Date of Patent: September 13, 2022Assignees: STMICROELECTRONICS RAZVOJ POLPREVODNIKOV D.O.O., STMICROELECTRONICS (ALPS) SAS, STMICROELECTRONICS SAInventors: Kosta Kovacic, Christophe Grundrich, Bruno Leduc, Anton Stern

Patent number: 10670666Abstract: A circuit includes, in series between a first terminal and a second terminal of application of a power supply voltage, and first and second branches. The first branch includes a first transistor and a first current source coupled to the first transistor. The second branch includes a resistive element, a second transistor coupled to the resistive element and forming a current mirror with the first transistor and a second current source coupled to the second transistor. The resistive element conditions a threshold of detection of a variation of the power supply voltage.Type: GrantFiled: July 27, 2018Date of Patent: June 2, 2020Assignee: STMICROELECTRONICS (ALPS) SASInventors: Bruno Leduc, Pascal Bernon, Stephane Clin

Patent number: 10139476Abstract: A rotary scanner is described. The rotary scanner includes a housing; a motor fixedly mounted relative to the housing; a structure mounted to the housing so as to be rotatable about a rotation axis by the motor; and a reflector assembly mounted to the structure via a pivot joint so as to be pivotable around a pivot axis between a rest angle and at least one other angle. The reflector assembly is biased to the rest angle and has a reflector plane parallel to the pivot axis. The rotary scanner also includes an optical source fixedly mounted relative to the housing and operable to emit an optical beam along the rotation axis and towards the reflector assembly during use; and a control interface allowing to control the rotation speed of the motor between a first rotation speed and at least one other rotation speed.Type: GrantFiled: January 20, 2017Date of Patent: November 27, 2018Assignee: INSTITUT NATIONAL D'OPTIQUEInventors: Bruno Leduc, Nichola Desnoyers
