Claim 9:
10. A correction method for the sensing circuit of claim 1, comprising:
supplying a third voltage signal from the first signal terminal to the in-phase input terminal of the operation amplifier, and supplying a first current signal from the second signal terminal to the integration capacitor and the anti-phase input terminal of the operation amplifier, by controlling the first switch, the third switch, and the fifth switch to be turned on and the second switch, the fourth switch, and the sixth switch to be turned off;
acquiring a third output voltage signal at the output terminal of the operation amplifier; and
calculating a correction value of the integration capacitor according to the third voltage signal, the third output voltage signal, and a capacitance of the integration capacitor.
