In this work we present a new version of the circuit VERDI (Versatile Readout for Detector Integration), namely VERDI-3, an integrated circuit designed for the readout of different type of radiation detectors, from nitrogen-cooled Ge and Si(Li) detectors, to silicon drift detectors (SDDs), to scintillation detectors, to photomultipliers tubes and others. VERDI-3 has been designed to achieve better noise performances in all configurations than its predecessors. The circuit is characterized by a revised programmable shaping amplifier and baseline holder, a new embedded biasing network and a revised SPI communication with added functions. The new VERDI shares the same advantages in terms of compactness for multielement detector integration and low power solution as for the rest of its family. The results of the experimental characterization of the circuit when used with different detectors are presented in this work.

Abstract

In this work we present a new version of the circuit VERDI (Versatile Readout for Detector Integration), namely VERDI-3, an integrated circuit designed for the readout of different type of radiation detectors, from nitrogen-cooled Ge and Si(Li) detectors, to silicon drift detectors (SDDs), to scintillation detectors, to photomultipliers tubes and others. VERDI-3 has been designed to achieve better noise performances in all configurations than its predecessors. The circuit is characterized by a revised programmable shaping amplifier and baseline holder, a new embedded biasing network and a revised SPI communication with added functions. The new VERDI shares the same advantages in terms of compactness for multielement detector integration and low power solution as for the rest of its family. The results of the experimental characterization of the circuit when used with different detectors are presented in this work.
