Test system of the time-over-threshold based chip optimized for linear transfer characteristics and low power for particle tracking applications

This paper presents the circuits and systems developed for testing the DSToTIC3 ASIC. Detailed study of the estimated noise performance in the presence of realistic external components is also a subject of this paper. DSToTIC3 is a prototype, 8-channel front-end electronics designed for the regime of long silicon strip sensors and interconnects of new tracking detectors. Layout and general architecture of the die is presented. Built-in digital-to-analog converters minimize the number of external components required for the chip operation, which makes it easily scalable to a final multichannel design.
