摘要: A dual positive-feedbacks voltage controlled oscillator includes an oscillation circuit and a cross coupled pair circuit. The oscillation circuit includes a first transistor, a second transistor, an inductor and a plurality of capacitors. The gates of the first and second transistors are opposite to each other and coupled to two points of the inductor. The inductor and the capacitors are formed as a LC tank. The cross coupled pair circuit includes a third transistor and a fourth transistor. The gates of the third and fourth transistors are cross coupled to two points of the inductor. Thereby, the gate of the third transistor is coupled to the gate of the second transistor; the gate of the fourth transistor is coupled to the gate of the first transistor; the drain of the third transistor is coupled to the source of the first transistor; and the drain of the fourth transistor is coupled to the source of the second transistor.
