The demanding requirements for pixel readout electronics for high-energy ph
ysics experiments and biomedical applications are reviewed. Some examples o
f the measured analog performance of prototype chips are given. The readout
architectures of the Pixel Readout fdr the ATlas Experiment (PIRATE) chip
suited for LHC experiments and of the Multi Picture Element Counter (MPEC)
counting chip targeted for biomedical applications are presented. First res
ults with complete chip-sensor assemblies are also shown. (C) 2000 Elsevier
