ABSTRACT:
A frequency synthesizer. The frequency synthesizer comprises a harmonic locked phase/frequency detector, a low pass filter, a voltage controlled oscillator, and a frequency divider. The harmonic locked phase/frequency detector receives a reference signal and a divided signal. The low pass filter is coupled to the harmonic locked phase/frequency detector. The voltage controlled oscillator is coupled to the low pass filter and provides an output signal. The frequency divider is coupled between the voltage controlled oscillator and the harmonic locked phase/frequency detector. Frequency of the divided signal is a harmonic frequency of the reference signal.
