ABSTRACT:
A method and system for fast wakeup of a high-Q oscillator (300) that includes a resonating element (304), preferably a crystal resonator (304), and an amplifier (310). The method comprises connecting the resonating element (304) to a fast wakeup, low-Q oscillator (302), inputting a plurality of pulses generated by the low-Q oscillator (302) into the resonating element (304), and simultaneously disconnecting the resonating element (304) from the low-Q oscillator (302) while connecting the resonating element (304) to the amplifier (310), thereby obtaining substantially uniform steady state oscillations in the high-Q oscillator. The system (300) includes in addition to high-Q and low-Q oscillator elements a mechanism for counting the pulses (312) and for performing the simultaneous disconnection and connection mentioned above.
