A DIGITAL FRONT-END AND READOUT MICROSYSTEM FOR CALORIMETRY AT LHC

A digital solution to the front-end electronics for calorimetric detec tors at future supercolliders is presented. The solution is based on h igh speed A/D converters, a fully programmable pipeline/digital filter chain and local intelligence. Questions of error correction, fault-to lerance and system redundancy are also being considered. A system inte gration of a multichannel device in a multichip, Silicon-on-Silicon Mi crosystem hybrid, is used. This solution allows a new level of integra tion of complex analogue and digital functions, with an excellent flex ibility in mixing technologies for the different functional blocks. It also allows a high degree of programmability at both the function and the system level, and offers the possibility of customising the micro system with detector-specific functions.
