New time-based readout (TBR) electronics has been developed and evaluated for its performance and application for PET detectors. It consists of a leading edge (LE) timing threshold for timing pickoff that provides a signal timing t1; a charge integration followed by a constant discharge between two specific timings t2 and t3 that are used to directly measure the signal energy. The timing-walk error...
An additional inner layer for the existing ATLAS Pixel Detector, called Insertable B-Layer (IBL), is under design and it will be installed by Phase I. New front-end readout ASICs fabrication (FE-I4) will replace the previous chips in this layer. The new system features higher readout speed - 160Mb/s per ASIC - and simplified control. The current data acquisition chains are composed of front-end and...
