The circuit for front-end electronics for neutron detection wall based on CPLD, which can deal with the output signal of the neutron detection wall in IMP, is introduced in this paper. An improved circuit design is proposed for front-end read-out electronics of neutron detection wall detector. The system consists of coincidence unit, QAC unit, TAC unit, and multiplexer unit etc. We use CPLD to construct the main circuit in the design. Compared with the circuits constructed by separate devices, the new circuit has features such as the DMOS switch used, higher precision, less components, lower cost and lower dissipation. The circuit we developed can be widely used in nuclear measurement system of physics experiment with large-scale detector array to form front-end read-out electronics of data acquisition system.
