This brief presents a fully differential K-band voltage-controlled oscillator (VCO) using commercial 0.18-μm SiGe BiCMOS process. By using triple-coupled LC tanks with strong coupling and varactor-controlled capacitor bank, the proposed VCO simultaneously achieves a wide tuning range, low phase nois...
