The VMM3a ASIC
IEEE Transactions on Nuclear Science（2022）
Abstract
The VMM3a is a custom low-noise application-specific integrated circuit. It is intended to be used in the front-end readout electronics of both the Micromegas and sTGC detectors of the ATLAS New Small Wheels upgrade project at CERN. It is fabricated in the 130-nm GlobalFoundries 8RF-DM process. The 64 channels with highly configurable parameters, although designed for a specific project, can meet the processing needs of signals from various detector types in several other applications. In this note, the VMM3a, which is the production version of the VMM family, will be presented along with the features incorporated and its performance.
