An injection-locked frequency divider (ILFD) with an inductive feedback for enhanced locking range has been developed in a commercial 0.13 m Si RFCMOS technology and compared with a conventional ILFD. The proposed ILFD showed a significant improvement in the locking range over the conventional ILFD, operating at a frequency range of 43.60-48.95 GHz. The dc power consumption of the ILFD was 0.58 mW with a supply voltage of 1.2 V for the divider core.Index Terms-CMOS integrated circuits, frequency division, injection locked oscillators.
A 20-30 GHz divide-by-3 ring-based injection locked frequency divider (ILFD) using NMOS loads for a wide locking range has been developed in a commercial 0.13-lm Si RFCMOS technology. The ILFD shows a locking range up to 7.5 GHz (20.8À28.3 GHz, 30.5%) and operation range of 10 GHz (20.8-30.8 GHz, 38.8%) with DC power consumption of 13 mW and a 1.5 V supply voltage. The fabricated circuit occupies only 0.008 mm 2 core area.
