INJECTION-LOCKED FREQUENCY DIVIDING APPARATUS
First Claim
1. An injection-locked frequency dividing apparatus, comprising:
- a frequency multiplier, for receiving a frequency signal and generating a multiple-frequency signal according to the frequency signal;
a first linear mixer and a second linear mixer, both coupled to the frequency multiplier for receiving the multiple-frequency signal, the first and the second linear mixer respectively receives a first input signal and a second input signal and mixes the multiple-frequency signal with the first input signal and the second input signal to generate a first mixed signal and a second mixed signal respectively, wherein a phase of the first input signal is complementary to a phase of the second input signal; and
an oscillator, coupled to the first linear mixer, the second linear mixer, and the frequency multiplier, for generating the frequency signal, and the oscillator further receives the first mixed signal and the second mixed signal for generating a first output signal and a second output signal according to the first mixed signal and the second mixed signal, wherein a phase of the first output signal is complementary to a phase of the second output signal.

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.
