Design of ultra-low noise power system for high-precision detectors
In this paper, we introduce an ultra-low noise power system designed for high precision detectors, like CCD detector. We build low noise power circuit for the front-end electronics, whose noise generally needs to be under 1 mVrms. Because the system may be used in low temperature environment as in Antarctica, the influence of electronic equipment working at 213K-193K is fully considered in the beginning of the design. As a result, the power system passed noise and long-time low temperature test.
