Flicker noise upconversion
WebApr 16, 2012 · This paper analyzes the flicker noise upconversion mechanisms in CMOS LC-VCOs, focusing on the bias circuitry and core cross-coupled pair, finding that the current-biased VCO has 1~2dB better phase noise/FoM at 1MHz offset due to the better amplitude noise control. 16 View 1 excerpt, cites background ... 1 2 3 4 5 ... References WebThis circuit is fabricated in a 0.35-μm CMOS technology together with a single-end-tuned oscillator and both cover the 2.0–2.4 GHz frequency range. The measured 1/ f3 phase noise at 10 kHz offset is −71 dBc/Hz, which outperforms the companion single-end tuning oscillator by 10 dB. Download to read the full article text References

WebFeb 1, 2014 · The phase noise of a ring oscillator can be obtained by multiplying its open-loop phase noise by a simple shaping function. The shaping function is computed using first principles and is applicable to both flicker-noise-induced and white-noise-induced phase noise, leading to compact equations for ring oscillators.
