Summary:In this paper the design of three stages used to read and amplifly the signals coming from 48 silicon photo multipliers sensors connected in parallel is presented. In the pre amplification stage a charge integrator circuit is proposed, in the addition stage, a simple adder circuit; and, in the final stage, a low pass multiple feedback filter. A circuit analysis of the stages is done taking into account the different noise sources, obtaining their respective tranfer functions in order to simulate the behavior of system. Finally, a set of values that meets the system requirements is found.
