Abstract
For example, a Local Oscillator (LO) generator may include a plurality of frequency sources configured to provide a respective plurality of frequency source signals according to a first frequency; and an injection-locked frequency divider configured to provide an LO signal having a second frequency. In one example, the second frequency may be based on the first frequency divided by a factor n. For example, the factor n may be an odd integer greater than one. For example, the injection-locked frequency divider may include a plurality of injection paths to inject the plurality of frequency source signals into an injection-locked Ring Oscillator (RO).
