摘要： A dynamic gearshifting system includes a monitoring device configured to monitor a duty cycle of a clock output signal of a crystal oscillator circuit during oscillation buildup upon power-up of the crystal oscillator circuit. The dynamic gearshifting system also includes a detecting device configured to detect whether the duty cycle of the clock output signal of the crystal oscillator circuit meets a duty cycle threshold value. The dynamic gearshifting system may further include an assertion device configured to assert a control signal based on detecting the duty cycle meets the duty cycle threshold value. The asserted control signal configured to dynamically adjust a transconductance of the crystal oscillator circuit.
