Abstract:
A sensor with a plurality of sensor elements (10), each of which includes a radiation-sensitive conversion element (1) which generates an electric signal in dependence on the incident radiation, and also with means (21 to 26) for amplifying the electric signal in each sensor element (10) and a read-out switching element (30) in each sensor element (10) which is connected to a read-out line (8) in order to read out the electric signal,characterized in thatthe means for amplifying include a respective source follower transistor (21) whose gate is connected to the conversion element (1), whose source is connected to an active load (23) and to one side of a sampling capacitor (26), the other side of the sampling capacitor (26) being connected to the read-out line (8) via the read-out switching element (30), and that a respective reset element (27) is connected to the conversion element (1) to reset the conversion element (1) to an initial state.
