Prototype of Front End Electronics based on FPGA-ADC for TOF PET detector applications

In non-coincidence mode, the ramp-like waveform is input into the FPGA by the signal generator and collected through FPGA-ADC. These data will be used for calibration of FPGA-ADC.

Single channel FPGA-ADC performs full waveform sampling. Charge integration will be performed after calibration. Energy resolution can be obtained through the energy spectrum of this system. Under the coincidence mode, the same ramp-like waveform is collected.
