Abstract
An oscillation circuit, a driving circuit thereof, and a driving method thereof are provided. The driving circuit generates a second enable signal according to an output signal of an oscillator and a first enable signal. The second enable signal is transmitted to the oscillator. When a number of waves of the output signal within a predetermined period is smaller than a predetermined value, the driving circuit adjusts a voltage level of the second enable signal. A voltage level of the first enable signal is equal to an enable voltage level. Through variations in voltage levels of the second enable signal, the oscillator is triggered to oscillate.
