VMM3a: an ASIC for Tracking Detectors

The VMM3a is a custom Application Specific Integrated Circuit (ASIC). It will be used as the front ASIC for both Micromegas and sTGC detectors of the ATLAS Muon New Small Wheels upgrade at CERN. Due to its highly configurable parameters, it has been proposed a variety of tracking detectors and another experiments. It is fabricated in the 130nm Global Foundries 8RF-DM process. The ASIC integrates 64 independently configurable channels each providing amplitude and timing measurements, in digital or analog format. The design aspects and performance of the VMM3a as a production ASIC will be presented.
