A frequency divider, which has a cross-coupled inductor-capacitor (LC) structure or a ring structure, is inputted with a direct current (DC) control voltage from an input terminal. By doing so, the frequency divider can adjust an oscillation frequency; and further compensate the input power sensitivity, lower the power consumption and increase the division range. The frequency divider can be used in high-band/high-speed digital or analog communication systems.
