Kurzfassung

NIKHEF (Amsterdam) and the University of Bonn made a joint effort to develop a front-end pixel chip prototype, named GOSSIPO-3, in IBM 130 nm standard CMOS technology for the readout of Micro Pattern Gas Detectors (MPGDs). This is a prototype for an application specific integrated circuit for the readout of position sensitive MPGDs. GOSSIPO-3 targets future highly granulated (60x60µm² per pixel) readout chips. The prototype consists of the analogue readout chain and the logic needed in a TPC application. This includes a high precision time to digital converter (TDC) with a sampling resolution of 1.7 ns and a dynamic range of 102 µs. The charge deposited in each pixel is measured using the time over threshold (ToT) technique in the dynamic range from 400 electrons to 28000 electrons with a standard deviation of 200 electrons. The circuitry is optimized for a low power consumption of roughly 100 mW/cm².
