Abstract:
A signal error calibrating method is disclosed herein and includes following steps: filtering an error voltage in a sensor by a low pass filter in a calibration mode; converting the offset voltage to be a digital offset signal by an analog digital signal converter; converting the digital offset signal to be an offset calibrating signal by a digital analog signal converter; transmitting the offset calibrating signal to an input end of the sensor so as to offset an error voltage at the input end of the sensor. After calibrating the error voltage, the analog digital converter in the error calibrating circuit can be used for the need of signal output and the low pass filter is turned off at the same time.

Claim (Index 6):
A signal error calibrating method, wherein the signal error calibrating method implements an error calibrating circuit and the error calibrating circuit including a low pass filter, an analog digital converter, an offset storage and a digital analog converter, the low pass filter electrically connected to an output end of a sensor, the analog digital converter electrically connected to the low pass filter, the offset storage electrically connected to the analog digital converter, the digital analog converter electrically connected to the offset storage, and another end of the digital analog converter electrically connected to an input end of the sensor, the method comprising steps:\n in a calibrating mode, filtering an offset voltage of a sensor by a low pass filter in a calibrating mode; converting the offset voltage to be a digital offset signal by an analog digital converter; converting the digital offset signal to be an offset calibrating signal by a digital analog converter; transmitting the offset calibrating signal to an input end of the sensor to offset an error voltage at the input end of the sensor; switching to a sensing mode from the calibrating mode when the error voltage is turned to be zero.
