Abstract
A circuit reducing phase noise of an oscillator includes a transistor, an impedance element coupled to the transistor, a inverting circuit coupled to one end of the impedance element, and an add circuit coupled to the inverting circuit and the other end of the impedance element, wherein the signals from the two ends of the impedance element is superimposed and sent out to reduce phase noise of an oscillator.
