Preamplifier design and analysis for dual output silicon photomultiplier
Listed in ScienceDB
[Background]: In order to apply in different scenarios of silicon-photomultiplier-coupled scintillator detector, Preamplifiers need to fulfill different requirements.
Description
[Purpose]: This study aims to design high-bandwidth, low-noise preamplifiers to cater for different output modes of silicon-photomultiplier-coupled scintillator detector. [Methods]: Based on OPA855 and consideration of bandwidth and noise, a transimpedance amplifier (TIA) and a voltage feedback amplifier (VFB) were designed.
The amplifier circuits were simulated and analysed using PSpice for TI software to obtain circuit parameters. Finally, the signal response and noise baseline level were measured, and signals of source were analysed using a silicon-photomultiplier-coupled Cerium-doped Gadolinium Aluminum Gallium Garnet (GAGG(Ce)) detector. [Results and Conclusions]: These preamplifiers have good gain stability.

TIA's bandwidth is 101MHz lower than VFB's 381MHz, but its baseline noise level is better than the VFB's . In addition, TIA is suitable for energy measurements and small-area SiPM applications, while VFB is more suitable for time measurements and large-area SiPM arrays.
