Abstract
A highly stable single chip resonator controlled oscillator with automatic amplitude control and biasing is designed for manufacture with monolithic integrated circuit technologies. Analog and digital output buffers with elaborate control for power saving purposes and sophisticated start-up and power-up circuits ensure, that a crystal controlled oscillation is safely induced at start-up and that the amplitude of oscillation is continuously controlled during operation to reach low phase noise and reduce power consumption of the circuit.
