Abstract
The detection circuit comprises a photodiode connected to a readout circuitry. The photodiode and readout circuitry are connected by means of a transistor arranged to operate as a closed switch when the readout circuitry biases the photodiode in a predefined range and to operate as an open switch in the other cases.
