Abstract; The Maximum Power Point Tracking controller (MPPT) is a key element in Photovoltaic systems (PV). It is used to maintain the PV operating point at its maximum under different temperatures and sunlight irradiations. The goal of a MPPT controller is to satisfy the following performances criteria: accuracy, precision, speed, robustness and handling the partial […]

Abstract; Porous silicon substrate is very promising for next generation wireless communication requiring the avoidance of high-frequency losses originating from the bulk silicon. In this work, new variants of porous silicon (PSi) substrates have been introduced. Through an experimental RF performance, the proposed PSi substrates have been compared with different silicon-based substrates, namely, standard silicon […]

Abstract; This work provides a new co-design methodology of ultrawide band (UWB) low-noise amplifier (LNA) with high out of band interference cancellation. The solution consists to cascade a selective microstrip UWB bandpass filter (BPF) with the proposed 0.18 μm complementary metal-oxide-semiconductor-based LNA. Indeed, the usefulness of this co-design technique is to address the interference mitigation […]

Abstract; In this paper, we report an experimental evidence of the impact of applied a low magnetic field (B <; 10 mT) during negative bias temperature instability (NBTI) stress and recovery, on commercial power double diffused MOS transistor. We show that both interface (ANit) and oxide trap (ANot) induced by NBTI stress are reduced by […]

Abstract: Forward and reverse current-voltage (I-V) of Ti/Au/n-Al0.33Ga0.67As/n-GaAs/n-Al0.33Ga0.67As multi-quantum well (MQW) Schottky diodes were measured over a range of temperatures from 20 to 400 K by a step of 20 K. The Schottky diodes parameters were then extracted from these characteristics. The Cheung method is used for this purpose, assuming a thermionic conduction mechanism. The extracted ideality factor decrease with increasing […]

Abstract; Fast, reliable and selective detection of microorganisms is of uttermost importance in clinical analysis, but also in food and water quality monitoring. In this study, we report on the construction of an immunosensor for sensitive and selective electrochemical detection of uropathogenic Escherichia coli (E. coli) UTI89 bacteria in aqueous and serum samples. We took benefit of […]

Abstract; Self-assembly through phase separation in block copolymers (BCPs) thin films represents an attractive route to create spontaneously ordered patterns at the sublithographic range. The cost effectiveness, the fast parallel processing time as well as the compatibility with the standard microelectronics technologies make it among the most promising techniques to meet the ever challenging feature […]

Abstract; An electrical response of a microflow sensor would open a wide horizon of uses and should intensify the integration of MEMS (Micro-Electro-Mechanical-System) microfluidic-based LOC (Lab-On-Chip). This paper presents an original microflow sensor which will be able to measure a low fluid flow rate. The sensor is designed and optimized using a multiphysics modelling and […]

Abstract; Zinc oxide (ZnO) thin films were deposited by pulsed laser deposition technique for making ZnO/Al/SiO2/Si Bulk and Surface Acoustic Wave (BAW and SAW) transducers. The aim is to improve the piezoelectric properties of the ZnO films, which are strongly linked to their texture and microstructure. ZnO films with a wurtzite structure were deposited on […]

Abstract; This paper focuses on the comparison of the RF performances of various advanced trap-rich (TR) siliconon-insulator (SOI) and porous silicon (PSi) substrates. The PSi substrates are produced by electroporisification starting either from cheap standard resistivity (10 Q·cm) silicon (PSi-S) or from the most widespread highly doped milliohm-centimeter Si wafers (PSi-M). Through small-signal RF measurements, […]
