In the framework of the INSERT project, the development of very accurate and reliable gamma cameras is of fundamental importance. For what concerns the readout electronics, one of the most challenging requirements is the design of front-ends immune to electromagnetic disturbances induced by the RF sequences of the MRI. Starting from the filter architecture already implemented in the ASIC of the ESA project, my doctoral activity will be focused on the design of an analog front-end able to process signals produced by 6x6 SDD matrices, according to new specifications regarding frame-rate, dynamic range, input leakage current and area. In order to make the signal transmission from the detection modules to the DAQ outside the MRI bores more immune to interferences, the on-chip integration of an analog-to-digital converter will be fully investigated.
