Abstract: An apparatus and a method for multiplying a frequency of an input signal are provided. The apparatus may include a main differential device for converting the input signal into a first differential signal and a second differential signal, a first multiplying device for outputting a first signal obtained by multiplying a frequency of the first differential signal, a second multiplying device for outputting a second signal obtained by multiplying a frequency of the second differential signal, and a compositing device for outputting a third signal obtained by combining the first signal and the second signal to remove a fundamental frequency component.
