Abstract
A frequency multiplier comprises a phase generator configured to receive an oscillation signal and to provide at phase generator outputs versions of the oscillation signal, which are phase-shifted with respect to each other. An injection-locked ring oscillator comprises a plurality of stages, wherein each of the phase generator outputs is coupled to a different stage of the plurality of stages for multi-point injection. A combiner combines output signals of the plurality of stages of the injection-locked ring oscillator into a signal having a frequency which is a multiple of a frequency of the oscillation signal.
