PANDA is a key experiment of the future FAIR facility, under construction at Darmstadt, Germany. The Micro Vertex Detector (MVD) is the innermost component of the experiment and its main task is to reconstruct the primary and secondary vertexes.
The PASTA (PAnda STrip ASIC) chip has been developed to read out the strip sensors of the MVD and its architecture is based on the Time-over-Threshold technique. Time to Digital converters with analog interpolators are used to obtain a very good time resolution with low power consumption.
A first full-size prototype was produced in a commercial 110 nm technology and is currently under test. An overview of the chip, of its readout systems and of the first results of its characterization will be presented.
