Development of Multi-channel Programmable SiPM Driver Board

General commercial SiPM driver boards are only available for certain models of SiPM. And this kind of driver board is unique for single-channel testing in the laboratory. This obviously does not apply to batch testing in large scientific engineering. Therefore, A new type of SiPM driver circuit has been developed which can realize the multi-channel test of SiPM. After detailed test, Self-designed SiPM driver circuit has the same test performances with the commercial one in voltage output, power ripple and temperature compensation function. A small batch of driver circuit testing has been conducted and comparing to the single circuit test, the conclusion is every board of the small batch test shows the same performance as the single board test within the margin of error.
