A 20–30 GHz divide‐by‐3 ring‐oscillator‐based injection locked frequency divider with a wide locking range

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. © 2011 Wiley Periodicals, Inc. Microwave Opt Technol Lett 53:389–841, 2011; View this article online at wileyonlinelibrary.com.
