ALICE plans to replace its Inner Tracking System during the second long shut down of the LHC in 2019 with a new 10 m(2) tracker constructed entirely with monolithic active pixel sensors. The TowerJazz 180 nm CMOS imaging Sensor process has been selected to produce the sensor as it offers a deep pwell allowing full CMOS in-pixel circuitry and different starting materials. [...]

A CMOS 0.18 μm 600 MHz clock multiplier PLL and a pseudo-LVDS driver for the high speed data transmission for the ALICE Inner Tracking System front-end chip
/ Lattuca, A (Turin U. ; INFN, Turin) ; Mazza, G (INFN, Turin) ; Rinella, G Aglieri (CERN) ; Cavicchioli, C (CERN) ; Chanlek, N (Suranaree U. of Tech.) ; Collu, A (Cagliari U. ; INFN, Cagliari) ; Degerli, Y (IRFU, Saclay) ; Dorokhov, A (Strasbourg, IPHC) ; Flouzat, C (IRFU, Saclay) ; Gajanana, D (NIKHEF, Amsterdam) et al.
This work presents the 600 MHz clock multiplier PLL and the pseudo-LVDS driver which are two essential components of the Data Transmission Unit (DTU), a fast serial link for the 1.2 Gb/s data transmission of the ALICE inner detector front-end chip (ALPIDE). The PLL multiplies the 40 MHz input clock in order to obtain the 600 MHz and the 200 MHz clock for a fast serializer which works in Double Data Rate mode. [...]

Monolithic Active Pixel Sensors (MAPS) offer the possibility to build pixel detectors and tracking layers with high spatial resolution and low material budget in commercial CMOS processes. Significant progress has been made in the field of MAPS in recent years, and they are now considered for the upgrades of the LHC experiments. [...]

Low-power priority Address-Encoder and Reset-Decoder data-driven readout for Monolithic Active Pixel Sensors for tracker system
/ Yang, P (Hua-Zhong Normal U.) ; Aglieri, G (CERN) ; Cavicchioli, C (CERN) ; Chalmet, P L (Unlisted, FR) ; Chanlek, N (Suranaree U. of Tech.) ; Collu, A (Cagliari U. ; INFN, Italy) ; Gao, C (Hua-Zhong Normal U.) ; Hillemanns, H (CERN) ; Junique, A (CERN) ; Kofarago, M (CERN ; Utrecht U.) et al.
Active Pixel Sensors used in High Energy Particle Physics require low power consumption to reduce the detector material budget, low integration time to reduce the possibilities of pile-up and fast readout to improve the detector data capability. To satisfy these requirements, a novel Address-Encoder and Reset-Decoder (AERD) asynchronous circuit for a fast readout of a pixel matrix has been developed. [...]

Low power, high resolution MAPS for particle tracking and imaging
/ Giubilato, P (Padua U. ; INFN, Padua) ; Cavicchioli, C (CERN) ; Chalmet, P (CERN) ; Kugathasan, T (CERN) ; Tobon, C Marin (CERN) ; Mattiazzo, S (Padua U.) ; Mugnier, H (CERN) ; Pantano, D (Padua U. ; INFN, Padua) ; Pozzobon, N (Padua U. ; INFN, Padua) ; Rousset, J (CERN) et al.
We describe here the first monolithic pixel detector prototype embedding the OrthoPix architecture, specifically designed to deal with imaging applications where the relevant number of pixel hit per frame (occupancy) is small (on the order or less than 1%), like in High Energy Physics, Medical Imaging and other applications. Current state of the art employs complex circuitry into the pixel cell to discriminate relevant signals, leading to an extremely effective, non-destructive compression at the price of large power consumption and pixel area limitations.
