Sinopsis

New Topics in Simulation and Modeling of RF Circuits addresses two main topics: simulation of RF circuits and new models of nonlinear power BAW resonators and filters.Since RF circuits have several unique features, and all analysis methods are based on the circuit essential properties, the book begins by describing the properties of RF circuits, characterization of circuits with customary and uncustomary behavior and some theorems of solutions existence and uniqueness for dynamic nonlinear circuits. Thereafter, the main time domain and frequency domain analysis methods for RF circuits are presented. The advantages and disadvantages of each method have been highlighted, and an algorithm for the time step choice in transient analysis based on energy balance errors is also presented. Lastly, the final part contains some nonlinear circuit models of power BAW resonators. The behavioral models for the time domain analysis are simple circuits containing weakly nonlinear elements. The behavioral models for frequency domain analysis are based on the measured values of the frequency dependent S parameters for a set of incident powers. S parameters corresponding to certain intermodulation products of practical interest are also considered. The physical models contain artificial transmission lines with nonlinear circuit elements corresponding to mechanical and electrical nonlinearities.

Acerca de los autores

Alexandru Gabriel Gheorghe obtained the engineering degree in 2004 and the Ph.D. in 2009, both in Electrical Engineering, from the University Politehnica of Bucharest, Romania, where he is currently a lecturer in the Department of Electrical Engineering. His scientific area of interest includes transient analysis algorithms, envelope following algorithms, and modeling and simulation of power BAW resonators and filters. Dr. Gheorghe published two books, one book chapter, 12 papers in international and Romanian journals, and 56 papers in conference proceedings and was director of two research projects.

Florin Constantinescu obtained the engineering degree in Electronics and the Ph.D. in Electrical Engineering from the University Politehnica of Bucharest, Romania, where he is currently a professor of Electrical Engineering. His scientific areas of interest are in circuit theory (qualitative properties of nonlinear circuits, symbolic analysis of linear circuits, synthesis of nonlinear resistive circuits, fast computation of the periodic steady state in nonlinear circuits) and RF circuits design (transient analysis algorithms, envelope following algorithms, modeling and simulation of power BAW resonators and filters). Prof. Constantinescu published nine books, one book chapter, 56 papers in international and Romanian journals, and 122 papers in conference proceedings. He was director of 18 research projects financed by Romanian and European institutions. Prof. Florin Constantinescu is an IEEE Senior Member since 1980 and was organizer and chairman of the IEEE Romanian CAS Chapter.
