Quasi-digital conversion for resistive devices: application in GMR-based IC current sensors

2013

Resistive devices, including sensors, are used in a huge range of applications within different scenarios. When a complete system is considered, a quasi-digital output is often recommendable. If the conversion is operated at device level, some problems such as noise disturbs, insertion losses and so on, can be reduced. In this work, we describe a resistance-tofrequency (R-f) converter with a suggested application in low current monitoring by means of GiantMagnetoResistance (GMR) sensors. Specific devices have been designed and microfabricated. The system has been tested by means of discrete components with a PCB. The complete microsystem monolithic integration in a standard CMOS technology …

Zasłużeni dla miasta. O mikrosystemie plateonimicznym Opola

2016

The Opole urban nomenclature has for many years been a space of special homage paid to the local heroes. Taking into account this fact, in my research I have concentrated on Opole streets, squares, buildings and estates named aftcr persons associated with this region. The analysis covered not only outstanding historical personalities, bul also contemporary authorities - writers, politicians and scientists. The purpose of this paper was to present the most important nomenclature trends associated with the regional history and to show the impact of names commemorating prominent historical figurcs on the contemporary image of Opole. This urban nomenclature microsystem eonsisting of about one h…

Monolithic integration of Giant Magnetoresistance (GMR) devices onto standard processed CMOS dies

2014

Giant Magnetoresistance (GMR) based technology is nowadays the preferred option for low magnetic fields sensing in disciplines such as biotechnology or microelectronics. Their compatibility with standard CMOS processes is currently investigated as a key point for the development of novel applications, requiring compact electronic readout. In this paper, such compatibility has been experimentally studied with two particular non-dedicated CMOS standards: 0.35 μm from AMS (Austria MicroSystems) and 2.5 μm from CNM (Centre Nacional de Microelectrònica, Barcelona) as representative examples. GMR test devices have been designed and fabricated onto processed chips from both technologies. In order …
