ABSTRACT:
A high signal-to-noise crystal oscillator is provided, including a transistor and a crystal coupled across the input thereof. The oscillator further includes series connected capacitors coupled across the crystal and between the base electrode of the transistor and reference potential with the emitter coupled to the junction of said series connected capacitors. The value of the series connected capacitor is selected to be such that the ratio of the total capacitance between the emitter to ground to the total capacitance between the base and emitter electrodes is on the order of 5.4 to 1 to 3.9 to 1.
