A.2020-01-242020-01-242016-11-281748-0221https://hdl.handle.net/2445/148635A versatile and reconfigurable ASIC is presented, which implements two different concepts of low level trigger (L0) for Cherenkov telescopes: the Majority trigger (sum of discriminated inputs) and the Sum trigger concept (analogue clipped sum of inputs). Up to 7 input signals can be processed following one or both of the previous trigger concepts. Each differential pair output of the discriminator is also available as a LVDS output. Differential circuitry using local feedback allows the ASIC to achieve high speed (500 MHz) while maintaining good linearity in a 1 Vpp range. Experimental results are presented. A number of prototype camera designs of the Cherenkov Telescope Array (CTA) project will use this ASIC.16 p.application/pdfengcc-by (c) Gascón Fora, David et al., 2016http://creativecommons.org/licenses/by/3.0/esCircuits electrònicsRaigs gammaInstruments astronòmicsElectronic circuitsGamma raysAstronomical instrumentsinfo:eu-repo/semantics/article6898392020-01-24info:eu-repo/semantics/openAccess
