Abstract

We analyse the performances of heterostructure field effect transistors (HFETs) for low-noise fast readout electronics for detectors of elementary particles. We discuss the advantages and the limits of these devices in comparison with silicon transistors. We also present the first integrated charge preamplifier fully based on HFETs and the experimental results obtained.
