Abstract :
A flexible, small, low-cost analog pulse shaper and amplifier circuit for Si PIN photodiode detectors is discussed. The shaping amplifier produces both a fast negative output signal with <10-ns risetime for timing measurements and a slow positive output signal with peaking times from 500 ns to 10 μs for energy measurements. The gains for the two signals can be set independently. The maximum output amplitude for the fast signal is -1.5 V, and +10 V for the slow signal. The resolution for the energy channel is <10-keV electronic contribution, giving a total of 17 keV with α particles. The resolution for the timing channel is <1-ns electronics with a total of 2 ns with α-particles
