The optimal processing of sensors — provided signal, imposes their integration on the same chip with the amplifier circuit. In this paperwork is analysed the structure, the operating conditions and the main features of some microsensors realised in the MOS and bipolar integrated circuits technology. There are also presented and described the(More)
The paper presents the results of research work regarding the analysis and optimization of magnetic microsensors realized in MOS integrated circuits technology. On the basis of adequate models these have been established the noise main characteristics for MOS-Hall plates and for double-drain MOSFET magnetotransistors. By using the numerical simulation the(More)
The paper presents a universal solution, simple and efficient to implement redundancy in electronic systems that process external signals. Is presented the structural schematic diagram of a redundant system in which notification of any defect and correct interpretation of the break signal is carried by comparing the output signal from the base unit to the(More)
Taking the best decisions, regarding maritime ship's manoeuvre requires the permanent acquaintance of the rolling and pitching values. The paper presents the possibility to use optic and magnetic sensors in monitoring measurement and warning naval equipment. There are described and analysed two original and reliable electronic systems which permit the(More)
The efficiency of generating the Hall electric field characterized by a material parameter, RH, called Hall coefficient. This depends on the type and concentration of the carrier, the scattering mechanism and even on the magnetic induction. This makes the analysis and optimisation of Hall devices very difficult. By conveniently choosing the material(More)
The optimal processing of sensors-provided signal, imposes their integration on the same chip with the amplifier circuit. In this paperwork is analysed the structure, the operating conditions and the main features of some microsensors realised in the MOS and bipolar integrated circuits technology.

The possibility of having the sensor and the amplifier circuit on the same chip has lead to the achievement of transducers with high conversion efficiency as well as an increase in their range of practical work. In this paperwork, based on the model of dual Hall devices, it is analysed the structure, the operating conditions and are established the response(More)
The growing necessity to increase the systems safety during running on board ships has imposed the method of block reserves. In the case of such redundant systems reliability behaviour is described by an assembly of reliability functions. The work presents these functions emphasising the ways to ensure a high reliability of naval equipment. This paper also(More)
