Original Abstract

A significant factor in demanding applications where precise synchronized triggering pulses (t < 1ns) are required consists in the use of high-quality oscillators operating at frequencies in the order of hundreds of MHz. The Butler crystal oscillator in connection with a common collector is suitable for this frequency range, not least because of the fact that the noted device is not prone to spurious oscillation. This article presents an investigation into the optimization of amplification margin at the oscillation frequency, the maximization of short-term frequency stability, and the minimization of power dissipation on the crystal section. For non-linear analysis of the oscillator, the harmonic balance method is used. Based on the method, we obtain the dependence of the crystal dissipated power on the damping resistor. The designated phase noise is recalculated to the crystal oscillator short-term stability, which constitutes a decisive point for the precise synchronization of triggering pulses.
