Millimeter Wave applications have been the key propellers on many fronts like 5G, autonomous cars, medical and so forth. ?In the millimeter-wave frequency band, one of the key components is the local oscillator which provides a stable and pure oscillating source to transfer the signal to the targeted channel. Yet millimeter-wave operation with advanced digital CMOS nodes is still challenging. Traditional circuit topologies used for communications at lower frequencies ported to millimeter-wave frequencies typically either do not work properly or require a large power consumption. This invention provides a subharmonic injection locking that allows for high-frequency operations with relatively low power consumption. Since the injection locked frequency tripler has two locking ranges around the two resonant frequencies of the VCO, a wide locking range is achieved when these two locking ranges overlap.
