Abstract :
Employing a switched-transformer-based triple-band Q-VCO and a magnetically-tuned multi-mode triple-push x4 injection-locked frequency multiplier (ILFM), a CMOS SDR frequency synthesizer generates IQ LO signals continuously from 0.37GHz to 23.25GHz and differential LO signals from 23.25GHz to 46.5GHz. Implemented in 65-nm CMOS, the synthesizer measures phase noise of -94dBc/Hz in band and of -136dBc/Hz at 10MHz offset from 7.2GHz and RMS jitters between 0.43ps and 0.55ps across the whole frequency range while consuming 36 to 90mW and occupying an active area of 1.82mm2.
