Study of vertex silicon detectors for LHC experiments

This thesis deals with the development of pixel and microstrip silicon detectors, to be used in the vertex system of LHC experiments. The presented chip for the readout of hybrid pixels is the baseline of the one foreseen for the ALICE experiment. The microstrip detector is the prototype for the VErtex LOcator of the LHCb experiment. The main aspects of the work related to a vertex detector are discussed, being the two sensor options in some sense complementary in covering the vertex system problems and requirements.
