Abstract
A highly stable single chip resonator controlled oscillator with automatic gain control designed for manufacture in monolithic integrated circuit technologies. An automatic gain controller monitors the output of a crystal controlled oscillator amplifier and produces a feedback signal to ensure oscillation is induced at startup and that the amplitude of oscillation is continuously controlled during operation to reach low phase noise and reduce power consumption of the circuit.
