Frequency analysis with coupled nonlinear oscillators

Auke Ijspeert, Jonas Buchli, Ludovic Righetti

We present a method to obtain the frequency spectrum of a signal with a nonlinear dynamical system. The dynamical system is composed of a pool of adaptive frequency oscillators with negative mean-field coupling. For the frequency analysis, the synchronizat ...

Oscillator Based on Suspended Gate MOS Transistors

Mihai Adrian Ionescu, Marco Mazza, Yogesh Singh Chauhan, Alexandru Rusu

The paper deals with the oscillator applications based on vibrating mode of the suspended gate SG-MOSFET transistor. In order to simulate the electrical behavior of the transistor a small-signal equivalent circuit of the gate is proposed and validated. An ...

Learning to move in modular robots using central pattern generators and online optimization

Auke Ijspeert, Jérôme Maye

This article addresses the problem of how modular robotics systems, i.e. systems composed of multiple modules that can be configured into different robotic structures, can learn to locomote. In particular, we tackle the problems of online learning, that is ...

Controlling swimming and crawling in a fish robot using a central pattern generator

Auke Ijspeert, Alessandro Crespi, Daisy Lachat, Ariane Pasquier

Online trajectory generation for robots with multiple degrees of freedom is still a difficult and unsolved problem, in particular for non-steady state locomotion, that is, when the robot has to move in a complex environment with continuous variations of th ...

General Modulation Strategy for Seven-Phase Inverters With Independent Control of Multiple Voltage Space Vectors

Drazen Dujic

This paper focuses on the analysis of a seven-phase voltage-source inverter for high-performance motor drives. The problem of the modulation strategy of the inverter is solved by combining the multiple space vector representation with traditional carrier-b ...

Spectral coarse graining and synchronization in oscillator networks

Paolo De Los Rios, David Gfeller

Coarse graining techniques offer a promising alternative to large-scale simulations of complex dynamical systems, as long as the coarse-grained system is truly representative of the initial one. Here, we investigate how the dynamical properties of oscillat ...

Frequency Synthesis for a Low-Power 2.4 GHz Receiver Using a BAW Oscillator and a Relaxation Oscillator

Christian Enz

In this paper, a solution to realize local oscillators (LO) for a low power super-heterodyne receiver is presented. The first oscillator uses a bulk acoustic wave (BAW) resonator with high Q-factor. A quasi- harmonic quadrature relaxation oscillator with l ...
