ABSTRACT
Most of the gamma-ray detectors employed in positron emission tomography (PET) applications provide output signals that need further amplifying and processing to carry out an optimal analog-to-digital conversion. Front-end electronics implement all the necessary analog processing from the detector’s output to the input of the data-acquisition and control (DAC) system. A typical front-end architecture usually includes an input preamplifying stage and an output shaping stage.
