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.

Abstract: This invention provides a light-concentrating structure with photosensitivity enhancing effect, including the substrate, buried layer, first electrode layer, second electrode layer, dielectric layer and interconnection structure. The substrate is equipped with a housing space; the buried layer is arranged above the substrate with the housing space; the first electrode layer is arranged above the buried layer; the second electrode layer is arranged in the middle of the first electrode layer; the dielectric layer is arranged above the second electrode layer; the interconnection structure is arranged above the substrate and the first electrode layer surrounding the dielectric layer, which forms an opening and a light-concentrating recess groove.
