Design of a Constant Fraction Discriminator for the VFAT3 front-end ASIC of the CMS GEM detector

In this work the design of a Constant Fraction Discriminator (CFD) to be used in the VFAT3 chip, currently under design for the read-out of the Triple-Gem detectors of the CMS experiment, is described. Simulations show that it is possible to extend the front-end shaping time in order to fully integr...

Descripción
Sumario:In this work the design of a Constant Fraction Discriminator (CFD) to be used in the VFAT3 chip, currently under design for the read-out of the Triple-Gem detectors of the CMS experiment, is described. Simulations show that it is possible to extend the front-end shaping time in order to fully integrate the GEM detector signal charge whilst maintaining optimal timing resolution using the CFD technique. A prototype chip containing 8 CFDs was implemented in 130 nm CMOS technology to prove the effectiveness of the proposed architecture before its integration in the VFAT3 chip. The CFD design and test results will be shown.
