Original Abstract
Direct digital synthesis is used in many applications. There is necessary to use a quality source of the clock signal. One of the best circuits for this purpose is Butler oscillator as emitter follower. By this circuit is possible to design a high frequency oscillator working up to hundred megahertz. In this paper the design of the Butler oscillator by use of a feedback loop analysis in resonance frequency vicinity of the crystal is showed. For non-linear analysis of the oscillator, the harmonic balance method is used.
