Abstract

We present a continuously tunable 52-to-61 GHz
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.
