|Title:||A Low-Flicker-Noise 30-GHz Class-F23 Oscillator in 28-nm CMOS Using Implicit Resonance and Explicit Common-Mode Return Path||Authors:||Hu, Yizhe; Siriburanon, Teerachot; Staszewski, Robert Bogdan||Permanent link:||http://hdl.handle.net/10197/11034||Date:||24-Apr-2018||Online since:||2019-08-26T13:19:53Z||Abstract:||This paper presents a millimeter-wave (mmW) frequency generation stage aimed at minimizing phase noise (PN) via waveform shaping and harmonic extraction while suppressing flicker noise upconversion via proper harmonic terminations. A 2nd-harmonic resonance is assisted by a proposed embedded decoupling capacitor inside a transformer for explicit common-mode current return path. Class-F operation with 3rd-harmonic boosting and extraction techniques allow maintaining high quality factor of a 10-GHz tank at the 30-GHz frequency generation. We further propose a comprehensive quantitative analysis method of flicker noise upconversion mechanism exploiting latest insights into the flicker noise mechanisms in nanoscale short-channel transistors, and it is numerically verified against foundry models. The proposed 27.3- to 31.2-GHz oscillator is implemented in TSMC 28-nm CMOS. It achieves PN of -106 dBc/Hz at 1-MHz offset and figure-of-merit (FoM) of -184 dBc/Hz at 27.3 GHz. 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)
