Abstract
The invention disclosed fast start-up single-pin crystal oscillation apparatus and operation method thereof. The apparatus comprises a comparator, an envelope detector, a trigger, a crystal, a finite state machine, an amplifier gain module, a load capacitor module and a bias resistor. Compared to prior arts, the invention uses a single-pin oscillator structure to remove two external load capacitors, reduces start-up time, increase negative resistance, reduce load capacitor, and uses fast start-up algorithm to make the oscillation circuit operating at optimal power-consumption.
