Image Sensors with In-situ Storage (ISIS) are being developed for use in future linear collider and fast imaging applications. The ISIS device consists of pixels each with a short charge storage register. Charge is collected by a photogate and stored in one of many in-pixel storage registers, for readout during quiet periods in the beam duty cycle. For an ILC application it is expected that...

The leading proposed technology for electromagnetic calorimeters
for ILC detectors is a highly granular silicon-tungsten calorimeter.
We have developed an active pixel sensor for such a calorimeter, which
would have extremely fine granularity, allowing binary pixel readout.
A first generation chip (TPAC1) has been fabricated, and this contains
a 168x168 pixel array, consisting of 50x50...

A new hybrid pixel readout integrated circuit denominated FE-I4 is being developed for use in ATLAS upgrades. The design goals include 4 times higher rate capability, 4 times the active area (full reticule), and 38% smaller pixels than the presently used FE-I3 IC. The target applications are a possible smaller radius replacement of the present inner layer and/or outer layers or disks of a...

With a growing need for high resolution, radiation hard and low mass pixel detectors the Micro-Pattern Gas Detector is a good candidate. This detector requires a dedicated front-end read-out chip with improved readout architecture to deal with the high data rate. In addition, it is highly required to keep power consumption as low as possible.
Some of prototype IC’s have already been submitted...

CMOS Monolithic Active Pixel Sensors (MAPS) have demonstrated their strong potential for tracking devices, particularly for flavour tagging. They are foreseen to equip several vertex detectors and beam telescopes. Most applications require high read-out speed, requiring sensors featuring digital output with integrated zero suppression. The most recent development of MAPS at IPHC and IRFU...

The NA62 experiment will need hybrid pixel sensors with a size of 300 um x 300 um and a time resolution of 150 ps (rms). To meet the timing requirement an adequate strategy to compensate the discriminator time-walk must be implemented and an R&D effort investigating two different options is ongoing. In this presentation we describe the two different approaches. One is based on the use of a...

We present the ASIC development of the readout electronics of the Gigatracker pixel detector of NA62. Gigatracker speed , noise and power performance are very challenging and 2 architectures , are in phase of R&D demonstration to further select the best approach. Circuits configuration of the constant fraction discriminator with on pixel TDC and of the time-over-threshold discriminator ...
