Abstract
A frequency generation device is provided. The frequency generation device includes a voltage generation unit configured to receive an input signal having an input frequency and to generate a feedback voltage based on the input signal, wherein the feedback voltage is proportional to the input frequency; and a feedback unit connected to the voltage generation unit and a reference voltage source, wherein the feedback unit is configured to receive a reference voltage from the reference voltage source and the feedback voltage from the voltage generation unit, so as to generate a feedback signal having a feedback frequency.
