The PASTA chip for the silicon micro strip sensor of the PANDA MVD — •Alberto Riccardi1, Kai-Thomas Brinkmann1, Valentino Di Pietro1, Tommaso Quagli1, James Ritman2, Angelo Rivetti3, Manuel Rolo3, Robert Schnell1, Tobias Stockmanns2, André Zambanini2, and Hans-Georg Zaunick1 for the PANDA collaboration — 1II. Physikalisches Institut Justus-Liebig-Universität Giessen, Giessen, Germany — 2Forschungszentrum Jülich — 3INFN Sezione di Torino, Torino, Italy
In the Micro Vertex Detector, which is the innermost detector of PANDA, there are two different types of sensors: hybrid pixel and double sided micro strips. My work is focused on the development of the ASIC readout for the strips, which in the PANDA experiment must cope with a hit rate up to 50 kHz per channel. The energy loss measurement of the particles crossing the silicon sensor is obtained by implementing the Time over Threshold technique.
The first PASTA (PANDA Strip ASIC) prototype is based on a Time to Digital Converter with an analog clock interpolator which combines good time resolution with a low power consumption. A full size chip was developed in a 0.11µ m CMOS technology and delivered in Autumn 2015. It features 64 channels with both analog and digital parts, a digital global controller, LVDS drivers and integrated bias.
In the presentation, an overview of PASTA and the results of the first tests will be presented.
