| Zusammenfassung: | A drift calibration circuit is provided. The drift calibration circuit includes a first instrument amplifier connected to a potentiometric sensor for receiving a sensing signal from the potentiometric sensor, and outputs a first signal; a inverting amplifier connected with the instrumentation amplifier for receiving the first signal, and outputs a inverting amplifier signal; a second instrumentation amplifier connected to the potentiometeric sensor for receiving the sensing signal from the potentiometric sensor, and outputs a first signal; a adder connects to the inverting amplifier and the second instrumentation amplifier for adding the inverting amplifier signal and the second signal, and outputs a response signal. |
