Simulation des circuits électroniques RF/Analogiques/Numériques excités par des signaux à modulation complexe

Abstract : The size, complexity and performances of modern wireless communication circuits are getting more and more challenging whereas marketing time and cost must be reduced as much as possible. In order to fill the current lack in CAD tools, this work is dedicated to the mixed simulation of complete communication systems driven by digital, analog baseband, quasi-periodic and digitally modulated RF signals. The first chapter of the thesis presents the various types of circuits and signals we want to simulate. The second part starts by describing the main RF simulation methods. Then we develop the innovations applied to Harmonic Balance method, based on an efficient spectrum use, and at last, several new contributions to the Envelope algorithm. The third chapter proposes a novel methodology to simulate RF/Analog/Digital complete circuits with an optimized Envelope algorithm : coupling with a digital simulator, behavioral models handling and analog/RF circuit partitioning. Finally, the last part demonstrates the functionalities of this new simulation technique on a few typical circuits. For the first time, complete mixed systems, described at logic, circuit and behavioral level, can be simulated in the same flow in reasonable times.
