ABSTRACT:
A crystal-controlled oscillator of integrated circuit design, comprising, a three-stage direct-coupled amplifier employing insulated gate field-effect-transistors and overall resistive negative (DC) feedback for bias stabilization thereof. The oscillator is designed to operate at a frequency at which the reactive network, including the inherent interelectrode capacitances of the field-effect-transistors, of the amplifier results in a loop phase shift which satisfies the Barkhausen Criterion.
