An injection-locked oscillator (ILO) with a self-biased injection circuit is proposed. By using the series-inductive peaking technique, the efficiency of the signal injection is considerably improved. Implemented in Global Foundries 65 nm bulk CMOS process, the proposed ILO demonstrated a 9 GHz locking range and can operate in 52–71 GHz with the tuning mechanism. Occupying a silicon area of 0.3 mm2, the circuit draws 13 mA from a 1.2 V supply including the output buffers.
