Abstract
A frequency synthesizing circuit comprising a first mixer configured to receive a first input signal, a first filter configured to receive an output of the first mixer and to remove undesired frequency signals from the output signal of the first mixer, and a feedback loop configured to provide an output of the first filter to an input of the first mixer. The feedback loop comprises a second mixer arranged within the feedback loop configured to receive the output of the first filter and to mix the output of the first filter with a second input signal.
