Abstract :
A flexible, small, and low-cost analog pulse shaper and amplifier circuit has been developed for silicon PIN photodiode detectors. The shaping amplifier produces both a fast negative output signal with less than 10-ns rise time for timing measurements and a slow positive output signal with peaking times from 500 ns to 10 μs for energy measurements. The gain for the two signals can be set independently. The maximum output amplitude is -1.5 V for the fast signal and +10 V for the slow signal. The resolution for the energy channel was <10 keV electronic contribution, giving a total of 17 keV with α particles. The resolution for the timing channel was <1 ns electronics, with a total of 2 ns with α particles. The whole circuit fits on a board of 7.5 cm×3.5 cm
