Description
The evolution of the technical design in the PET scanning industry aims to reduce the radiation dose and shorten the scanning time. To achieve this ambitious goal, it is essential to develop a PET experiment and test benches for the characterization of new scintillation materials.
One important part of the readout path is a fast-amplifying stage that decouples a high-capacity photosensor array from the acquisition electronics. The goal of this work is to design a low-noise amplifying stage with a high bandwidth. The low-distortion differential amplifier could be utilized for a PET application. A practically implemented readout board for MPPC based on ADA4960-1 demonstrates a promising performance. The best combination of slew rate, bandwidth, and broadband distortion. These attributes allow it to drive a wide variety of MPPC arrays.
