    abstract = {This paper presents a 60 GHz Quad-Core push-push VCO in 45 nm partially depleted Silicon-on-Insulator (SOI) CMOS. The measured phase noise (PN) at 60.5 GHz is −101.7 dB/Hz at 1 MHz offset from carrier. The continuous frequency-tuning range (FTR) is 19 %. The Quad-Core VCO consumes only 40 mW DC power. The complete circuit including fundamental and second harmonic (H2) output buffers draws 110 mA from a single 1 V supply. The VCO cores are coupled via resonant-tank transformers. A similar transformer-coupled Dual-Core VCO is fabricated and measured to prove the relative PN improvement between Dual-Core and Quad-Core topology. The total area of the Quad-Core VCO excluding pads is 0.1 mm2.},

    push-push cross-coupled voltage-controlled oscillator (VCO) in
    a 28 nm bulk CMOS technology. The second harmonic is
    extracted in a non-invasive way using a transformer. The
    primary side acts simultaneously as a second harmonic filter
    and a balun. The VCO achieves in measurement a low phase
    noise of -87 dBc=Hz at 1 MHz offset at 60 GHz and
    an output power of -23 dBm. The VCO including buffers
    dissipates 49 mA from a single 0:9 V supply, while the VCO
    core consumes only 12 mA. It occupies a chip area of only
    0:28 mm2 including pads. The VCO achieves a continuously
    tunable frequency tuning range (FTR) of 16%. The circuit is
    suitable for 60 GHz FMCW radar applications.
