A small die area and wide locking range CMOS frequency divider

This letter proposes a new injection-locked frequency divider (ILFD) with wide locking range and small die area. The proposed CMOS ILFD consists of an injection MOS and an LC tank voltage-controlled oscillator with a cross-coupled switching pair and tunable active inductors. The divide-by-2 ILFD was fabricated in the 0.18-μm 1P6M CMOS technology. At the supply voltage of 1.8 V, the divider free-running frequency is tunable from 1.46 to 2.7 GHz, and at the incident power of −4 dBm the locking range is about 3.4 GHz (79%), from the incident frequency of 2.6 to 6.0 GHz. The core power consumption is 7.2 mW and the die area is 0.383 × 0.379 mm2. © 2007 Wiley Periodicals, Inc.
