A low-voltage differential injection locked divider with forward body bias

An low voltage and wide locking range injection-locked frequency divider using a 0.13-μm CMOS is presented. The wide locking range and low-voltage operation are achieved by using forward body bias technique. A differential injection scheme is proposed to fit to the integrated differential on-chip oscillator and improve injection efficiency. When operating at a supply voltage of 0.6 V, a maximum locking range of 10.31 GHz, from the incident frequency 40.49 to 50.8 GHz, is achieved at the incident power of 0 dBm. The frequency divider consumes a static current of 6 mA.
