Title: Signal generator having fine resolution and low phase noise

Abstract: A signal generator includes an oscillator, a phase locked loop and a fractional divider. The oscillator is configured to provide an output signal. The phase locked loop is configured to receive the output signal and to provide a tuning signal to the oscillator. The phase locked loop has a phase detector configured to receive the output signal, to compare the output signal to a reference signal, and to provide the tuning signal to the oscillator based on the comparison. The fractional divider is outside of the phase locked loop and is configured to generate the reference signal.
