    Abstract
  • The technology of far ultraviolet photon-counting imaging detection is to record each single photon position and achieve the purpose of general imaging by detecting weak single photon information. The counting rate limits the information acquisition. On the basis of analyzing factors affecting the counting rate, the front-end analog circuit is needed for the amplification and shaping of the detector signals. Eventually, A225 chip was chosen as the pre-amplifier and shaping circuit was designed in the analog front-end circuit. Corresponding simulation and experimental results show that the circuit design is reasonable, and the counting rate can reach 200kHz.
