• LC-tank oscillator
• wide-locking range

A new wide-locking range multi-modulus LC-tank injection locked frequency divider (ILFD) is proposed and was fabricated in a 0.18 mu m CMOS process. The ILFD circuit is realized with a complementary MOS LC-tank oscillator and an injection composite composed of an inductor in series with an injection MOS. The two output terminals of the injection composite are connected to the resonator outputs. The ILFD can be used as a first-harmonic oscillator (ILO), even-modulo or odd-modulo oscillator depending upon the incident frequency of injection signal. At the supply voltage of 1.5 V, the free-running frequency is from 4.85 to 5.13 GHz, the current and power consumption of the divider without buffers are 2.78 and 4.17 mW, respectively. At the incident power of 0 dBm, the locking range in the divide-by-1(2, 3, 4) mode is from the incident frequency 3.72 to 8.69 (8.42 to 10.95, 13.66 to 16.03, 19.13 to 20.5) GHz.
