| Zusammenfassung: | The present invention discloses a method and an apparatus of the drift calibration of sensors. The method includes shifting the sensing signal and differential technology to remove the drift signal by time during a long measuring. The apparatus includes two voltage sensors and readout circuits, a signal-shifting circuit and a differential circuit, and the apparatus is used for outputting the response signal without time drifting. |
