A 60GHz Wide Locking Range CMOS Frequency Divider using Power-Matching Technique

A 60GHz injection-locked frequency divider with power-matching technique is designed in 0.13-mum CMOS technology for wide locking range. Compared with shunt-peaking version, the power-matching technique utilized in injection-locked frequency divider improves locking range by 15% based on simulation results. The measurement results show the divider free-running frequency is 30.4 GHz and the total locking range is 6 GHz (10%) at the input power of 3 dBm while consuming 8.8mW from a 1.2 V power supply.
