  • Patent number: 12160212
    Abstract: A sensor offset voltage compensation circuit includes a programmable gain amplifier (PGA) having an input loop configured to receive the signal output by a sensor (e.g., a voltage generated a sensor resistive bridge of a pressure sensor) and an output loop configured to furnish an output signal having a voltage that is greater than the input voltage. An offset compensation voltage is applied to at least one of the input loop or the output loop of the PGA to at least substantially cancel the zero-quantity offset voltage of the sensor from the output voltage.
    Type: Grant
