1. An oscillation device, comprising:
a control circuit, generating a control signal and coupled to a supply voltage; and
a ring oscillation circuit, coupled to said control circuit, starting oscillation at a first signal frequency from no starting oscillation and generating an oscillation signal with said first signal frequency while said supply voltage is raised to a supply voltage level, then adjusting an oscillation frequency according to said control signal for driving the frequency of said oscillation signal to become from said first signal frequency to a second signal frequency, and said second signal frequency higher than said first signal frequency.
