Abstract

Recently the need for a higher level of integration in x-ray and gamma ray sensor systems has lead to several approaches of integrating read out electronics in a monolithic integrated circuit (IC). Typically these ICs are limited in their application to a specific problem. The Readout Electronics for Nuclear Applications (RENA) Integrated Circuit, presented here, is targeted for use in many energy sensor applications. The RENA IC has 32 parallel signal channels with, signal polarity control for use with either electron or hole collection from detectors. The input amplifier is optimized for a detector capacitance of 6 pF, but may be used with detector capacitances up to 50 pF. The Shapers' peaking time is digitally selectable, for optimum noise filtering, with peaking times geometrically spaced from 400 ns to 6 microsecond(s) . Up to 16 RENA ASICs may be daisy chained together to make a system with 512 detector channels. Various trigger modes are available with a user- defined threshold over the full signal range of 50K electronics. The circuits in the RENA are designed to be stable with no 'tweaking' control,s which allows an easy user interfaces.
