Abstract
An electromagnetic radiation detection circuit includes a photodetector transforming the received electromagnetic radiation into an electric current. A readout circuit is coupled to a first terminal of the photodetector and configured to transform a current signal into a voltage signal. A capacitor has a first terminal electrically coupled to the first terminal of the photodetector and a second terminal electrically coupled to the readout circuit. A resistor has a first terminal electrically coupled to the capacitor and to a first terminal of the photodetector. A bias circuit is electrically coupled to a second terminal of the resistor and configured to bias the photodetector during a first time period by means of the resistor.
