Abstract

VCO designs have evolved from single-resonant LC-tank VCOs to the recent multi- resonant RLCM(Resistor-Inductor-Capacitor-Mutual-inductance) tank VCOs that allow reshaping of VCO phase-noise (PN) impulse sensitivity function (ISF). Two recent RF VCOs [1, 2] exploited the 2∩d−harmonic resonance to impede the flicker- noise upconversion, achieving an FoM@1MHz of up to 195.4dBc/Hz (Fig. 26.2.1). Specifically, the RLCM tank in [1] tailors a multi-turn inductor with a positive mutual coupling factor (k>0) to generate an implicit common-mode (CM) resonance at 2(F0SC)(0) 50% [2]⇑⇑ 00SC2F0SC1f2 0 1f3 [1, 2] (CDM)
