Abstract :
We discuss design issues related to the extensive use of Enclosed Layout Transistors (ELT´s) and guard rings in deep submicron CMOS technologies in order to improve radiation tolerance of ASIC´s designed for the LHC experiments (the Large Hadron Collider at present under construction at CERN). We present novel aspects related to the use of ELT´s: noise measured before and after irradiation up to 100 Mrad (SiO/sub 2/), a model to calculate the W/L ratio and matching properties of these devices. Some conclusions concerning the density and the speed of IC´s conceived with this design approach are finally drawn.
