Constant fraction discriminator pdf writer

In this work the design of a constant fraction discriminator (CFD) to be used in the VFAT3 chip for the read-out of the triple-GEM detectors of the CMS experiment, is described. A prototype chip containing 8 CFDs was implemented using 130 nm CMOS technology and test results are shown.

Given an input pulse, the leading edge discriminator produces an output pulse at the time when the input pulse crosses a given threshold voltage. This, however, causes a problem in situations where the timing was important. If the amplitude Constant Fraction Discriminator Created by Christopher O'Grady, last modified by Melchiorri, Riccardo on Oct 17, 2022 This script lives in /reg/g/psdm/tutorials/examplePython3/cfd.py and demonstrates how to run a constant-fraction-discriminator algorithm on a waveform (similar to a peak-finder for area-detectors).
However, the energy threshold in the cfd is set by a leading-edge discriminator. This discriminator is set to prevent the sensitive zero-crossing comparator firing on electronic noise. A schematic circuit diagram of a constant-fraction discriminator is shown in Figure 5.6. f delay crossing zero one shot output circuit sum constant fraction
Development of a monolithic constant fraction discriminator Abstract: A constant fraction discriminator was developed with a bipolar application-specific IC (ASIC) technology from NEC without a delay. It is called the differentiation constant fraction discriminator (DCFD). Prototype chips were examined for their integrity and performance.
