Abstract
Embodiments of a reference path circuit and communication device are generally described herein. The reference path circuit may include an injection locked multiplier (ILM) and a group of one or more buffer amplifiers. The ILM may receive a sinusoidal reference signal from a reference oscillator at a reference frequency. The ILM may generate a sinusoidal ILM output signal at an ILM output frequency that is based on an integer multiple of the reference frequency. The integer multiple of the reference frequency may be within a locking range of the ILM that may be based on a resonant frequency of the ILM. The group of one or more buffer amplifiers may generate an output clock signal for input to the frequency synthesizer. The output clock signal may be based on a sign function of the ILM output signal.
