Abstract

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-μm Si RFCMOS technology.The ILFD shows a locking range up to 7.5 GHz (20.8-28.3 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 mm2 core area.
