Abstract
An electromagnetic radiation detection circuit includes a photodetector transforming the received electromagnetic radiation into an electric current. A bias circuit is connected to the photodetector. An amplifying circuit has an input terminal coupled to the photodetector. An amplifying transistor has a first low-impedance electrode forming the input terminal of the amplifying circuit and a second low-impedance electrode coupled to an output terminal of the detection circuit. The transistor is configured to conduct the current applied on the first electrode. A high-impedance electric load is connected to the second electrode to deliver a voltage representative of the electric current originating from the photodetector.
