In this paper, we have studied the sources of error of a low-cost 3-axis MEMS accelerometer by means of Power Spectral Density and Allan Variance techniques. These techniques were applied to the signals acquired from ten identical devices to characterize the variability of the sensor produced by the same manufacturer. Our analysis showed as identically produced accelerometer have somehow variable...
Quantum computers could efficiently solve problems that are intractable by today's computers, thus offering the possibility to radically change entire industries and revolutionize our lives. A quantum computer comprises a quantum processor operating at cryogenic temperature and an electronic interface for its control, which is currently implemented at room temperature for the few qubits available...
In this paper, we report on the design, fabrication and characterization of a low cost, portable detection system able to quantify, in a rapid and reliable way, the contamination level of Ochratoxin A (OTA) in red wine. The operating principle is the real-time monitoring of the natural fluorescence of OTA molecules during a chromatographic run on a thin layer chromatographic plate. The fluorescence...
A 32-channel ASIC has been designed and fabricated in a standard 0.35 μm CMOS technology for the read-out of Gas Electron Multiplier detectors to be used for beam monitoring in hadron therapy applications. Each analog channel is based on the classic CSA+shaper architecture, followed by a peak detector which works as an analog memory during the read-out phase. An analog multiplexer routes the outputs...
