This paper presents a methodology for parameters extraction of photovoltaic cell based on real measurement. The modeling of equivalent schemes of solar cells is of great importance in order to be included in electric circuits for wireless sensor networks power supply. The parameters extraction of these devices is still a very difficult task, which requires experimental data, computing and modeling...
One of our most vital resources nowadays is fresh water. Water quality refers to the condition of the water, including chemical, biological and physical characteristics with respect to its suitability for a particular purpose. The main purpose of this publication is to set up a virtual system for water analysis in order to measure particular parameters of the water before and after physicochemical...
In this paper we have examined the back-bias effect and its influence on Hall microsensor's behavior, which is manufactured on 0,18 µm CMOS technology. Then the sensor's parametric reliability was tested at the temperature range of −40°C to +150°C. The purpose of the constructed Hall cell is to improve sensor's characteristics, achieving high sensitivity with minimal parasitic offset effects.
The requirements for precision integrated sensors are constantly increasing and the new techniques in the circuit design are of great importance. In this paper a new technology approved Hall effect microsensors are presented, which experimentally prove improved sensor's characteristics.
