Patent number: 11581880Abstract: Series of first ramps and second ramps are generated. A circuit delivers a first signal representative of the comparison of each first ramp with a set point and delivers a second signal representative of the comparison of each second ramp with the set point. Based on the first and second signals: a first ramp is stopped and a second ramp is started when the first ramp reaches the set point, and a second ramp is stopped and a first ramp is started when the second ramp reaches the set point. The value of the set point is modulated in response a maximum value of the first/second last ramp compared with the set point.Type: GrantFiled: November 11, 2021Date of Patent: February 14, 2023Assignee: STMicroelectronics (Rousset) SASInventors: Vincent Binet, Michel Cuenca, Ludovic Girardeau

Publication number: 20220163408Abstract: A calibration method of a temperature sensor is provided. The temperature sensor having a current source and a ring oscillator generating a square pulse signal with a temperature-dependent square pulse frequency. The acquisition of a first square pulse frequency measurement at a first temperature from the square pulse signal forms a first measurement point. A second square pulse frequency measurement at a second temperature from the second square pulse signal forms a second measurement point. The determination of the relation data being representative of an affine relation between square pulse frequency measurements and temperatures. The affine relation being defined by a used proportionality coefficient modified with respect to a measured proportionality coefficient of a measured affine relation linking the first measurement point and the second measurement point.Type: ApplicationFiled: October 25, 2021Publication date: May 26, 2022Inventors: Vincent Binet, Bruno Gailhard
