Abstract :
An analog chip is designed to receive from a PM, through a 50 Ω coaxial cable, signals rising in 3 ns, falling in 8 ns, and to provide: • l signals for timing purposes, lixed analog output, proportional to the input, for spectral measurements; are 8 channels per chip with a common gain adjustment for the preamplifier, and individual control for the offset and threshold setting. The discriminator sensitivity is 2 mV. The dynamic range is from 2 to 100 mV. The noise equivalent at the input is ≈100 μV. The RMS time dispersion is less than 550 ps for 3 mV threshold. The shaping amplifier is of bipolar shape with 80 ns peaking time and 2.5 V mean output voltage. The cross talk between channels is less than 2%.
