- Abstract
This research studies the RF performance of a wide locking range divided-by-3 injection-locked frequency divider (ILFD) in BiCMOS process. The newly designed ILFD circuit bases on capacitive cross-coupled oscillator with dual-resonance RLC resonator and uses dual-injection technique. It uses one linear mixer and one non-linear harmonic mixer in the frequency conversion. The power consumption of the ILFD core is 5.6 mW and the locking range is from 6.8 to 11.8 GHz (53.76%) at injection power Pinj = 0 d Bm. Measured tuning range shows the dual-band property without frequency tuning hysteresis and is from 3.73 to 2.69 GHz while varactor control voltage is tuned from 0 to 2 V.
