ALEXANDRIA, Va., Dec. 23 -- United States Patent no. 12,506,456, issued on Dec. 23, was assigned to InvenSense Inc. (San Jose, Calif.).
"Dynamic capacitance-to-volvage offset cancellation" was invented by Federico Mazzarella (Milan) and Vadim Tsinker (San Jose, Calif.).
According to the abstract* released by the U.S. Patent & Trademark Office: "In a microelectromechanical system (MEMS) sensor, movement of a component such as a proof mass due to a force of interest is sensed capacitively. A capacitance-to-voltage (C2V) converter receives a capacitance signal from the sensor and outputs a signal that includes an offset in addition to a signal of interest. The output signal is analyzed to identify the offset portion of the output signal and ...
