The object of the invention is a magnetic system for absolute force measurement with improved linearity. The proposed invention belongs to the field of magnetic systems, in particular to the field of contactless magnetic systems with a field probe to measure the magnetic signal and create the output signal response in the relation to the force. The force is therefore the input and the electrical signal is the output.

COBISS.SI-ID: 9312852Electronic Impedance Spectroscopy (EIS) is well known method for measurements of bio-chemical interactions and properties of the bio-chemical sensors under different conditions. Such measurements are very useful for many different applications like environmental monitoring, bio-medical applications, in vitro sensing of the brain neural networks, etc. Because of that it make sense to design and build a measurement platform based on integrated circuit electronics implemented in a short channel CMOS technology. For such measurements there are numerous instruments available, however only for the measurements of one sensor impedance in on time. If more sensor responses must be measured at the same time and in real time to preserve spatial and temporal resolution, no instrument exists. In this article we present a measurement system platform that is possible to integrate and which can perform precise real time measurements of complex impedances on the array of sensors.

COBISS.SI-ID: 9005652In this paper we discuss a possibility to simplify modeling and simulation of testing strategy of high-resolution Δ∑ modulators. The methodology could be used for production as well as for real time built-in self-tests. We show that a pseudo-random signal is a good option for a signal source and that test method leads to efficient and cost-effective testing that can also be used for real time built-in self-tests. The method is theoretically analyzed and verified using Matlab simulations. The models of DUT (device under test) and reference digital circuits are simulated and the difference is demonstrated with simple area-efficient algorithm/hardware.

COBISS.SI-ID: 9405268In the presentation field test results of the portable THz system are presented. Scene capture was done in different weather conditions such as rain, cold weather and fog. Higher level of moisture in the air can cause poor reception THz signal, but results of scene capture shown that at the 5m distance resolution of the system is still high. Presentation also includes results of thermal simulation of THz sensors at different biasing and different air pressure is presented.
