Low noise 4-channel front end ASIC with on-chip DLL for the upgrade of the LHCb Calorimeter

An integrated circuit for the Upgrade of the LHCb Calorimeter front end electronics is presented. It includes four analog channels, a Delay Locked Loop (DLL) for signal phase synchronization for all channels and an SPI communication protocol based interface. The analog circuit is based on two fully...

description An integrated circuit for the Upgrade of the LHCb Calorimeter front end electronics is presented. It includes four analog channels, a Delay Locked Loop (DLL) for signal phase synchronization for all channels and an SPI communication protocol based interface. The analog circuit is based on two fully differential interleaved channels with a switched integrator to avoid dead time and it incorporates dedicated solutions to achieve low noise, linearity and spill-over specifications. The included DLL is capable of shifting the phase of the LHC clock (25 ns) in steps of 1 ns. The selected technology is AMS SiGe BiCMOS 0.35 um.
