Abstract—A novel circuit topology suitable for the imple-
mentation of CMOS voltage-controlled oscillators (VCOs) at
millimeter-wave frequencies is presented in this paper. By em-
ploying transmission line segments to transform the admittance of
the additional cross-coupled pair , the proposed LC-tank VCO can
sustain fundamental oscillation at a frequency close to the
/109/97/120
of the transistors. Using a standard 0.18
m CMOS process, a
V-band VCO is realized for demonstration.
