• A 5-GHz-band highly linear frequency tuning voltage-controlled oscillator (VCO) using 0.35μm SiGe BiCMOS technology is presented. The highly linear VCO has a novel resonant circuit that includes two spiral inductors, p-n junction diode varactor units and a voltage-level-shift circuit. The fabricated VCO exhibits a VCO gain from 224 to 341MHz/V, giving a Kvco ratio of 1.5, which is less than one-half of that of a conventional VCO. The measured phase noise is -116dBc/Hz at 1MHz offset at an oscillation frequency of 5.5GHz. The tuning range is from 5.45 to 5.95GHz. The dc current consumption is 3.4mA at a supply voltage of 3.0V.
