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