The resulting 1/f3 phase noise (PN) can be an issue in PLLs with a loop bandwidth of <;1MHz, which practically implies all cellular phones. A previously published noise-filtering technique  and adding resistors in series with gm-device drains  have shown significant reduction of the 1/f3 oscillator PN corner. However, the former needs an additional tunable inductor and the latter degrades PN in the 20dB/dec region.||Funding Details:||European Research Council||Type of material:||Conference Publication||Publisher:||IEEE||Copyright (published version):||2015 IEEE||Keywords:||1f noise;CMOS integrated circuits;Capacitors;Harmonic analysis;Inductors;Oscillators;Resonant frequency||DOI:||10.1109/ISSCC.2015.7063117||Language:||en||Status of Item:||Peer reviewed||Is part of:||Proceedings of 2015 IEEE International Solid-State Circuits Conference (ISSCC) 2015||Conference Details:||2015 IEEE International Solid-State Circuits Conference (ISSCC), San Francisco, California, USA, February, 2015|
