Patent ID: 7928387

Claim:
A device for detecting infrared radiation comprising an array of bolometric detectors which are sensitive to the incident radiation and are referred to as “active”, and a single bolometer which is insensitive to said radiation and is referred to as “blind”, formed on a substrate in which a read circuit is produced for sequentially addressing each of the rows of detectors of said array, each of the active bolometers in a single row being biased simultaneously, wherein said read circuit also comprises: means of producing a reference current (I ref ) based on said single blind bolometer; means of simultaneously copying and applying said reference current (I ref ) to a plurality of current integrators; and wherein said means of simultaneously copying and applying said reference current and one column of the array are directly connected to a common input of one of said plurality of current integrators; said plurality of current integrators, each designed to integrate the difference between the current flowing through the simultaneously biased active bolometer of the row which is currently being read and said thus copied and applied reference current; and wherein said plurality of current integrators integrate said current difference all at the same time.
