ABSTRACT:
A method for self-calibrating a sensor can be implemented in a system having a calibration circuit. The calibration circuit has differential circuitry which compares an output signal of the sensor with a predetermined reference signal associated with a reference property. A bias controller increments or decrements the sensor operating bias according to the deviation between the predetermined reference signals and sensor output signal such that the sensor output corresponds to the predetermined reference voltage. The calibration circuit can be embedded in the sensor to provide a self-calibrating sensor. Logic circuitry can be used to form the calibration circuit.
