Abstract
An injection-locked frequency dividing apparatus including a frequency multiplier, a first linear mixer, a second linear mixer, and an oscillator is disclosed. The frequency multiplier receives a frequency signal and generates a multiple-frequency signal accordingly. The first and the second linear mixer both receive the multiple-frequency signal and respectively receive a first input signal and a second input signal, wherein the phases of the first and the second input signal are complementary. The first and the second linear mixer respectively mix the multiple-frequency signal with the first and the second input signal to respectively generate a first mixed signal and a second mixed signal. The oscillator generates the frequency signal. The oscillator further receives the first and the second mixed signal and generates a first output signal and a second output signal accordingly, wherein the phases of the first and the second output signal are complementary.
