The front‐end electronic circuitry plays a fundamental role in determining the performance obtained from ultrafast and highly sensitive photodetectors. In this paper we deal with electronic problems met working with single photon avalanche diodes for detecting single optical photons and measuring their arrival time with picosecond resolution. We describe an active quenching circuit capable of driving the detector in a remote position, connected with a coaxial cable. By minimizing the noise of…
