Front-end Electronics for the ATLAS Tile Calorimeter

The ATLAS Tile Calorimeter readout is designed to measure energy depositions in a single cell from ~30 MeV to 2 TeV. Signals up to 800pC must be processed over a dynamic range of 16 bits. More than 10,000 channels of front-end readout electronics are needed for this detector. This paper presents the design of the front-end readout electronics and its test results.
