Abstract
A multiphase oscillator suitable for 15/30-GHz dual-band applications is presented. In the circuit implementation, the 15-GHz half-quadrature voltage-controlled oscillator (VCO) is realized by a rotary traveling-wave oscillator, while frequency doublers are adopted to generate the quadrature output signals at the 30-GHz frequency band. The proposed circuit is fabricated in a standard 0.18-μm CMOS process with a chip area of 1.1 × 1.0 mm2. Operated at a 2-V supply voltage, the VCO core consumes a dc power of 52 mW. With a frequency tuning range of 250 MHz, the 15-GHz half-quadrature VCO exhibits an output power of -8 dBm and a phase noise of -112 dBc/Hz at 1-MHz offset frequency. The measured power level and phase noise of the 30-GHz quadrature outputs are -16 dBm and -104 dBc/Hz, respectively. © 2007 IEEE.
