Abstract :
A monolithic dual-channel preamplifier chip for LAr calorimetry has been designed in three “flavours”. Four wafers containing about 500 units have been fabricated and the best flavour was carefully evaluated to establish the yield and the uniformity of the process at cryogenic temperatures. The results of this evaluation are presented.
