Integrated receiving circuit for radiofrequency signals comprising: an amplifying element (2) using the multiplication zone (5) of a reverse biased semiconductor junction (3, 4) operating in Geiger mode for amplifying an input radiofrequency signal (Vin) a ...
In this work we introduce the use of the per-band link control method in cascades of distributed fiber Raman amplifiers (DFRAs) for compensating power transients of WDM channels. By using two compensation channels, each one controlled by a proportional-int ...
We report on the structural and electronic interface formation between ITO (indium-tin-oxide) and prototypical organic small molecular semiconductors, i.e., CuPc (copper phthalocyanine) and alpha-NPD (N,N'-di(naphtalen-1-yl)-N,N'-diphenyl-benzidine). In pa ...
We present the analysis and design of reflecting cells capable of dynamically and independently control the reflection phase of each component of a dual-polarized impinging wave. Such capability is of significant interest for the future implementation of d ...
Gallium nitride (GaN) is one of the most interesting materials for devices applications such as blue light emitting diodes, laser diodes and high power and high temperature electronic applications, because of its large band gap (3.39 eV). Several growth te ...
An efficient hybrid method to optimize the phase states distribution, or phase diagram, of a digitally-reconfigurable reflective cell is presented. It allows minimizing phase quantization errors in applications such as reflect arrays. Digital control of th ...
We present a linear multicast of an analog signal in a two-pump self-seeded parametric device. The linearity of the parametric multicasting is assessed by two-tone measurements of the third-order intermodulation products and radio-frequency spectral analys ...

A very wideband slot antenna with reconfigurable stopband is presented. The reconfiguration is achieved by modifying the effective length of an embedded stopbandresonator by means of three pairs of PIN diodes. Four different operative states—three of them ...
This paper presents a recently introduced switching principle for emerging monolithic bidirectional devices. Based on the hypothesis that those switches may overcome conventional diode type solutions in power converters, an active self-switching process be ...

This paper presents a new modeling methodology accounting for generation and propagation of minority carriers that can be used directly in circuit-level simulators in order to estimate coupled parasitic currents. The model is based on a new compact model o ...
