Abstract
An apparatus relates generally to the generation of an oscillating signal. In this apparatus, a fractional-N generator is for receiving a frequency control word and a reference signal. A multiplying injection-locked oscillator is coupled to the fractional-N generator for receiving a clock signal for outputting an oscillating signal. A frequency tracking loop is coupled to the fractional-N generator for receiving the clock signal, and further coupled to the multiplying injection-locked oscillator for receiving the oscillating signal.
