This book fills the need for a comprehensive volume on the most recent research on oscillator circuit design, analysis and application. It highlights developments in the analysis of synchronization and wave phenomena, new analytical and design methods and their application, and novel engineering applications of oscillator circuits.

Topics covered include various oscillatory circuits and their synchronization; bifurcation analysis of oscillatory circuits; synchronization phenomena of hysteresis oscillators; recent research on memristor based relaxation oscillators; theory and design of fractional-order oscillators; piecewise-constant oscillators and their applications; multimode oscillations in hard oscillators; wave propagation of phase difference in coupled oscillator arrays; coupled oscillator networks with frustration; fundamental operation and design of high-frequency high-efficiency tuned power oscillator; graph comparison and synchronization in complex networks; experimental studies on networks of coupled chaotic oscillators; ring oscillators and applications in random bit generation; attacking on-chip oscillators.

Oscillator Circuits: Frontiers in Design, Analysis and Applications is essential reading for researchers, students and designers working in circuit theory, analysis, design and application.
