A Silicon Photomultiplier Based Detection System with Integrated Feature Extraction

This paper presents a silicon photomultiplier (SiPM) based sensor with integrated feature extraction module. SiPMs are used in many applications such as time of flight measurements, fluorescence lifetime estimation, underwater wireless optical communication, quantum computing, high-resolution imaging, and particle physics. In order to facilitate signal processing such as timing, energy, and periodic events, feature extraction is integrated with the SiPM readout. The feature extractor consists of a peak detector, a sign bit generator, an integrator, a pulse width detector, and a digital output generator. The average power consumption is 2.12 mW.
