Original Abstract

A lot of applications, for example Direct digital synthesis, is necessary using very quality crystal oscillator using crystal on higher overtone. One of the best circuits is Butler oscillator as emitter follower. This allows design oscillator on high frequency, until hundred megahertz. In this paper is showed design Butter oscillator in 67108864 Hz using simulation feedback loop narrow resonance frequency crystal. In the Matlab is showed influence individually elements in circuit. This is important for design oscillator with low phase noise (high short-term stability) and stability amplitude of signal in output. The design is oriented to maximum short-term stability.
