The frequency doubler has a first transistor, a second transistor, a first inductor and a second inductor. A first terminal of the first transistor and a first terminal of the second transistor are at a common voltage. The frequency doubler receives the in-phase oscillating signal and the inverse oscillating signal via control terminals of the first and second transistors. The first and second inductors couple a second terminal of the first transistor and a second terminal of the second transistor to an output terminal of the frequency doubler, respectively.
