Autonomous Microwave Circuits

This book facilitates a sound understanding of the free-runningoscillation mechanism, the start-up from the noise level, and theestablishment of the steady-state oscillation. It deals with theoperation principles and main characteristics of free-running andinjection-locked oscillators, coupled oscillators, and parametricfrequency dividers.

Analysis and Design of Autonomous Microwave Circuitsprovides:

• An exploration of the main nonlinear-analysis methods, withemphasis on harmonic balance and envelope transient methods

• Techniques for the efficient simulation of the most commonautonomous regimes

• A presentation and comparison of the main stability-analysismethods in the frequency domain

• A detailed examination of the instabilization mechanisms thatdelimit the operation bands of autonomous circuits

• Coverage of techniques used to eliminate common types ofundesired behavior, such as spurious oscillations, hysteresis, andchaos

• A thorough presentation of the oscillator phase noise

• A comparison of the main methodologies of phase-noiseanalysis

• Techniques for autonomous circuit optimization, based onharmonic balance

• A consideration of different design objectives: presetting theoscillation frequency and output power, increasing efficiency, modifying the transient duration, and imposing operation bands

Analysis and Design of Autonomous Microwave Circuits is avaluable resource for microwave designers, oscillator designers, and graduate students in RF microwave design.
