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.engjournal articlehttp://dx.doi.org/10.1088/1748-0221/11/11/P11017http://iopscience.iop.org/open access539.1ThresholdScottTime.Física nuclear2207 Física Atómica y Nuclear
