In this paper we present an RF PA employing an output impedance matching network of the pi-type, where an inductor is variable. In order to implement this tunable inductor, the coupled-inductor technique [1] is used. Although other techniques for inductor ...
This article presents a novel approach for implementing ultra-low power digital components and systems using source-coupled logic (SCL) circuit topology, operating in weak inversion (sub-threshold) regime. PMOS transistors with shorted drain-substrate cont ...
The design of distributed amplifiers in a CMOS process is investigated. In particular, the impact of parasitic elements from the transistors and from interstage inductors is studied. A methodology for determining an optimum design, including the number of ...
We demonstrate that it is possible to filter all image with an elliptic window of varying size, elongation and orientation with a fixed computational cost per pixel. Our method involves the application of a suitable global pre-integrator followed by a poin ...

An interactive Java applet for real-time simulation and visualization Of the transmittance properties of multiple interference dielectric filters is presented. The Most commonly used interference filters as well as the state-of-the-art ones are embedded in ...
We use a Fourier-space imaging technique relying on outcoupling grating probes to study the coupled mode interaction and dispersion properties of guided modes in silicon-on-insulator codirectional couplers. Our approach allows us to measure the mode splitt ...
We present the microfabrication and characterization of a reciprocating-type poly(methylmetacrylate) (PMMA) ball-valve micropump which is actuated with a high-performance and compact electromagnetic circuit of centimeter size. We have improved by finite el ...
A completely scalable lumped-circuit model for horizontal Hall devices is presented therein that can be efficiently implemented in SPICE-like simulators. The model has been employed for the quantitative analysis of. a) geometrical, b) temperature, and c) f ...

As a result of the ever growing number of functionalities and standards to be supported by communication systems, as well as the constant development of radar and imaging technologies, a key research area in the field of microwaves and millimeter waves is ...
The adjunction of constrictions along the meander of a superconducting Fault Current Limiter (FCL) greatly improves its behavior thanks to a better distribution of the dissipative zones at the occurrence of a short circuit. This design works perfectly for ...
