Abstract
A radiation sensor means for detecting a radiation comprises a radiation sensor element outputting a current which is generated by the incident radiation power, a detection circuit detecting the current generated by the radiation sensor element, and a reset circuit connected to the radiation sensor element in such a way that, when said reset circuit is driven by a reset signal, the charge carriers produced by the incident radiation power recombine at a rate which is higher than the rate without the reset signal, the reset signal being adapted to be applied to said reset circuit by means of the detection circuit.
Claims13
A radiation sensor means for detecting a radiation incident thereon, comprising
- at least one radiation sensor element outputting a current which is generated by the incident radiation power;
- and
- a detection circuit detecting the current generated by the radiation sensor element;
- wherein
- the radiation sensor element is a transistor having a gate, a source, a drain and a substrate terminal;
- and
- the radiation sensor means comprises a reset circuit, which, when it has a reset signal applied thereto, establishes a connection between the substrate terminal and the source terminal of the transistor so that the charge carriers produced by the incident radiation power recombine at a rate which is higher than the rate without the reset signal, the reset signal being adapted to be applied to said reset circuit by means of the detection circuit.
