Project: APFEL (Apd Panda Front-end ELectronic)



For the electromagnetic calorimeter (EMC) of the PANDA experiment a preamplifier and shaper is under development. The designed application specific integrated circuit (ASIC) is optimized for the readout of APDs with a capacitance of 300 pF. On each ASIC two equivalent readout channels and a serial interface are implemented. The results of the second iteration realized in a 350 nm CMOS process are presented in the attached documents.


  • Sep. 2005: Start the ASIC development / first calculations
  • Nov. 2005: Submission 1st iteration / proof of concept
  • Feb. 2006: 1st iteration / electronic test
  • Mai. 2007: Submission 2nd iteration / design improvement
  • Aug. 2007: 2nd iteration / parameter specification
  • Dec. 2007: 2nd iteration / first detector test
  • Feb. 2010: Submission 3rd iteration / canditate for final design
