A millimeter-wave multiphase voltage-controlled oscillator (VCO) is presented. In order to facilitate high-frequency oscillation and to minimize the phase error caused by the device and layout mismatch, a rotary traveling-wave topology based on transmission lines with inductive loading is employed for the circuit implementation. Using a 0.18-mum CMOS process, the fabricated VCO provides half- quadrature output phases at 32 GHz. The measured output power and phase noise at 1-MHz offset are -9 dBm and -108 dBc/Hz, respectively. Operated at a supply voltage of 1.2 V, the power consumption of the proposed circuit is 54 mW.
