Abstract :
In this paper, we present a 39.1-to-41.6 GHz 1.2 V 64 mW DeltaSigma fractional-N frequency synthesizer that is implemented in 90nm CMOS. To reduce power consumption, a divide-by-4 injection-locking frequency divider (ILFD) is used in the feedback loop and a digital calibration technique is implemented to overcome the ILFD locking-range limitations.
