  • Method and system to improve power utilization using a calibrated crystal warm-up detection
    Patent number: 8917147
    Abstract: A calibrated crystal warm-up method that can include determining the number of clock cycles of a crystal clock reference signal from a crystal oscillator occur during a single clock cycle of a low-power oscillator. Further, the determination can occur when the crystal oscillator is warmed up. The method can also include comparing a number of clock cycles of the crystal clock reference signal with a previously determined number of clock cycles of the crystal clock reference signal to indicate whether the crystal oscillator is warmed up. Further, the method can include counting the number of clock cycles of a low-power clock reference signal have occurred up until the time it has been determined that the crystal oscillator has been warmed up.
