Patent number: 11561663Abstract: A touchscreen resistive sensor includes a network of resistive sensor branches coupled to a number of sensor nodes arranged at touch locations of the touchscreen. A test sequence is performed by sequentially applying to each sensor node a reference voltage level, jointly coupling to a common line the other nodes, sensing a voltage value at the common line, and declaring a short circuit condition as a result of the voltage value sensed at the common line reaching a short circuit threshold. A current value level flowing at the sensor node to which the reference voltage level is applied is sensed and a malfunction of the resistive sensor branch coupled with the sensor node to which a reference voltage level is applied is generated as a result of the current value sensed at the sensor node reaching an upper threshold or lower threshold.Type: GrantFiled: September 30, 2020Date of Patent: January 24, 2023Assignee: STMicroelectronics S.r.l.Inventors: Calogero Marco Ippolito, Angelo Recchia, Antonio Cicero, Pierpaolo Lombardo, Michele Vaiana

Patent number: 11275100Abstract: An amplification interface includes an input terminal receiving a sensor current and an output terminal supplying an output voltage. An analog integrator is connected to the input terminal and supplies the output voltage. A current generator is connected to the input of the analog integrator and generates a compensation current based on a drive signal.
