Conseil Européen pour la Recherche Nucléaire is currently undergoing a major upgrade within the A Large Ion Collider Experiment (ALICE) detectors, one of the four main experiments at the Large Hadron Collider (LHC) accelerator. The LHC luminosity will increase making the heavy ions collision rate rise from 500 Hz to 50 kHz. Both the time projection...

During the last decades we have witnessed the performance improvement and the aggressive growth of the complexity of integrated circuits (ICs). The progressive size reduction of transistors in recent technological nodes has allowed and even compelled IC designers to perform analog tasks in the digital domain, increasing the demand for analog-to-dig...

This work presents the design of a low-power 10-bit 12-MS/s Successive Approximation Register (SAR) Analog-to-Digital Converter (ADC) in 65-nm technology, suitable for IEEE 802.15.4g standard frontend receivers (low data rate and power consumption smart utility networks). By using the differential implementation with a pair of boot-strapped switche...

The upgrade of the ALICE TPC will allow the experiment to cope with the high interaction rates foreseen for the forthcoming Run 3 and Run 4 at the CERN LHC. In this article, we describe the design of new readout chambers and front-end electronics, which are driven by the goals of the experiment. Gas Electron Multiplier (GEM) detectors arranged in s...

A Large Ion Collider Experiment (ALICE) has been conceived and constructed as a heavy-ion experiment at the LHC. During LHC Runs 1 and 2, it has produced a wide range of physics results using all collision systems available at the LHC. In order to best exploit new physics opportunities opening up with the upgraded LHC and new detector technologies,...

This work performs, for the first time, a comparative study between the die areas of two inverter gates, where the first one is implemented with conventional p-type and n-type MOSFFETs (rectangular gate geometries) and the second one is implemented with a conventional p-type MOSFET and a FISH n-type MOSFET (hybrid inverter layout) in order to verif...

Neste trabalho o aluno estuda o processo de fabricação de circuitos integrados da AMS de 0.35µm, através do programa educacional do MOSIS, e utiliza o software IC Station para o desenvolvimento das máscaras em geometria convencional e Fish. Fabricados, seguindo as regras de processo, os leiautes serão caracterizados no laboratório do Centro Univers...
