Abstract
The ABCD design is a single chip implementation of the binary readout archi tecture for silicon strip detectors in the ATLAS Semiconductor Tracker. The prototype chip has been manufactured successfully in the DMILL process. In the paper we present the design of the chip and the measurement results. T he basic analogue performance of the ABCD design has been evaluated using a prototype SCT module equipped with the ABCD chips. The digital performance has been evaluated using a general purpose IC tester. The measurements con firmed that all blocks of the ABCD design are fully functional and the chip s meet all basic requirements of the SCT. Wafer screening has been performed using a customised wafer tester. The set -up allows measurements of all analogue and digital parameters at the nomin al clock frequency of 40 MHz as well as evaluation of speed margins for the digital blocks. The ABCD chips have been irradiated separately with X-rays up to a total do se of 10 Mrad, with neutrons from a nuclear reactor up to a fluence of 2x10 (14) n/cm(2) and with a high energy proton beam up to a fluence of 3x10(14) p/cm(2). The test that were performed confirmed satisfactory radiation har dness of the DMILL technology and of the ABCD design up to the radiation le vels expected in the SCT.
