Study of readout architectures for triggerless high event rate detectors at CLIC

In this work possible readout architectures for future detectors at CLIC are discussed. These detectors will need a triggerless readout electronics with amplitude and time reconstruction and they may operate with very high event rates (≥ 1 hits / channel / bunch train of 156 ns). The main subject of this study, both theoretical and experimental, is a readout based on the deconvolution principle. The basic principle, the performance, the advantages and limitations of this technique are discussed. In the case of extremely high event rates (> 4 hits / channel / bunch train) a readout based on a gated integrator and correlated double sampling is proposed.
