Circuit Features of Multichannel Chips of Reading Electronics of Silicone Photomultiplier Tubes

The main trends in the design of readout electronics chips for silicone photomultipliers (SPM) are analyzed. The results of the circuit design of a charge-sensitive amplifier (CSA) with an adjustable conversion factor and a base line restorer (BLR circuit) for this type of sensor are considered. The electrical circuit of the CSA is shown and its operation is considered in detail. The advantages of the developed CSA with its application in multichannel chips of signal processing of the SPM are described.
