A 2.45-GHz self-adaptive rectifier based on a two-way Gysel power divider (PD) with switch networks (SN), an impedance transform network (ITN), feedback (FN) and two rectifiers is developed in this paper. The SNs ITN are controlled by FN according to output voltages. single-path mode at low level switches two-path high level. It has been simulated, fabricated tested. original input range when e...

Dielectric spectroscopy is one of the most commonly used techniques for the investigation of the dynamic response of glass-forming materials. The tremendous slowdown of the particle motions when approaching the glass transition and especially the fast processes in glass-forming materials, which have come into the focus of scientific interest recently, make the investigation in a wide frequency ...

Orly Yadid-Pecht, MEMBER SPIE Ben-Gurion University of the Negev Electrical and Computer Engineering Department P.O. Box 653 Beer-Sheva 84105 Israel E-mail: [email protected] Abstract. The work done to provide image sensors (CCDs and CMOS) with a wide dynamic range is reviewed. The different classes of solutions, which consist of logarithmic sensors, ‘‘clipped’’ sensors, multimode sensors, frequ...

A bidirectional multi-resonant DC/DC converter is proposed in this study. The structure of the symmetrical, and operating characteristics operation mode are same. Adopting synchronous driving, can regulate output voltage over a wide range. Regardless forward or reverse mode, switches realise zero-voltage switching entire gain be zero due to its similar notch filtre. transmit fundamental wave th...
