|Title:||A 30-GHz Class-F23 Oscillator in 28nm CMOS using harmonic extraction and achieving 120 kHz l/f3 Corner||Authors:||Hu, Yizhe; Siriburanon, Teerachot; Staszewski, Robert Bogdan||Permanent link:||http://hdl.handle.net/10197/11035||Date:||7-Nov-2017||Online since:||2019-08-26T13:31:25Z||Abstract:||This paper presents a mmW frequency generation stage aimed at minimizing phase noise via waveform shaping and harmonic extraction while suppressing flicker noise upconversion via proper harmonic terminations. A second-harmonic tank resonance is assisted by a proposed embedded decoupling capacitor inside a transformer for shortest and well controlled common-mode current return path. Class-F operation with third-harmonic boosting and extraction techniques allow maintaining high quality factor of a 10 GHz tank at the 30 GHz frequency generation while providing implicit divide-by-3 functionality. The proposed 27.3-31.2 GHz oscillator is implemented in 28-nm CMOS. It achieves phase noise of-106 dBc/Hz at 1-MHz offset and figure-of-merit (FoM) of -184 dB at 27.3GHz. Its flicker phase-noise (1/f3) corner of 120 kHz is an order-of-magnitude better than currently achievable at mmW.||Funding Details:||European Commission - Seventh Framework Programme (FP7)
