Abstract
A voltage-controlled oscillator includes a first transistor, a second transistor, a first center-tapped inductor, two first varactors, a second center-tapped inductor and two second varactors. The first and second transistors cooperatively forma cross-connected pair. The first center-tapped inductor and the first varactors cooperatively form a first LC tank. The second center-tapped inductor and the second varactors cooperatively forma second LC tank. The cross-connected pair is connected between the first and second LC tanks. The first and second center-tapped inductors are mutual-inductively coupled to each other. An oscillation signal pair is provided between the first LC tank and the cross-connected pair.
