The conventional front-end electronics for PET imaging consist of an energy circuit and a timing circuit. A single channel in front-end electronics typically requires several amplifiers, an ADC and a TDC. In this paper, we present a novel front-end electronic design using 1-bit sigma-delta ($\boldsymbol {\Sigma }$ -$\boldsymbol {\Delta }$ ) modulation and an FPGA. The new design requires only one...
The feature-extraction algorithm, developed for the digital front-end electronics of the electromagnetic calorimeter of the PANDA detector at the future FAIR facility, is implemented in VHDL for a commercial 16 bit 100 MHz sampling ADC. The use of modified firmware with the running on-line data-processing algorithm will allow to perform realistic performance studies of the calorimeter and test a trigger-less...
