US Patent Issued to STMicroelectronics on Sept. 23 for "Read circuit for capacitive sensors, corresponding sensor device and method" (Italian Inventors)

ALEXANDRIA, Va., Sept. 23 -- United States Patent no. 12,425,777, issued on Sept. 23, was assigned to STMicroelectronics S.r.l. (Agrate Brianza, Italy).

"Read circuit for capacitive sensors, corresponding sensor device and method" was invented by Paolo Angelini (Bologna, Italy) and Roberto Pio Baorda (Casarile, Italy).

According to the abstract* released by the U.S. Patent & Trademark Office: "A read circuit for capacitive sensors such as a MEMS microphones includes a sensor node configured to be coupled to a capacitive sensor to apply a bias voltage to the sensor and sense the capacitance value of the sensor wherein the voltage at the sensor node is indicative of the capacitance value of the capacitive sensor. A switch is provided betwee...
