ABSTRACT:
The temperature dependency of an oscillator can be reduced by a method and circuit that uses two positive feedback paths to provide the positive feedback necessary for maintaining the oscillation of an LC-oscillating circuit. One of the two feedback paths compensates the temperature dependent influences while the other compensates temperature independent influences.
