An ultra wide-band ÷3 injection-locked frequency divider

An ultra wide locking range divide-by-3 injection-locked frequency divider (ILFD) using a standard 0.18 μm CMOS process is presented. The ILFD circuit is realized with a cross-coupled n-core MOS dual-resonance RLC-tank oscillator with linear mixer to extend the locking range. The core power consumpt...

More Information
Summary:An ultra wide locking range divide-by-3 injection-locked frequency divider (ILFD) using a standard 0.18 μm CMOS process is presented. The ILFD circuit is realized with a cross-coupled n-core MOS dual-resonance RLC-tank oscillator with linear mixer to extend the locking range. The core power consumption of the ILFD core is 7.39 mW. The divider's free-running frequency has dual-bands at 3.79 and 2.37 GHz by switching the varactor's control bias, and at the incident power of 0 dBm the locking range is 6.8 GHz (71.58%), from the incident frequency 6.1 to 12.9 GHz.
