Title:
INFRARED SENSOR AND INFRARED SENSOR ARRAY
Document Type and Number:
WIPO Patent Application WO/2006/043384
Kind Code:
A1
Abstract:
An infrared sensor includes: a series capacity element and a reference capacity element each indicating a predetermined capacity value; an infrared detection capacity element whose capacity value is varied according to the intensity of the infrared ray incident to the element; and an output node connecting one terminal of the series capacity element, one terminal of the reference capacity element, and one terminal of the infrared detection capacity element. By applying a predetermined voltage between the other terminal of the series capacity element and the other terminal of the reference capacity element, the potential of the output node is set to be a reference potential; and by applying a predetermined voltage between the other terminal of the series capacity element and the other terminal of the infrared detection capacity element, the potential of the output node is set to be a detection potential. The intensity of the infrared ray is outputted as a potential difference between the reference potential and the detection potential.
