PASSIVE PHASED INJECTION LOCKED CIRCUIT

摘要

The present invention relates to passive phased injection locked circuit and ring-based voltage controlled oscillators. A passive phased injection locked circuit comprises first and second transmission lines, each has a plurality of discrete elements, that are operative to deley the phase of AC signal. Between the first and second transmission lines, a capacitor network is formed to advance the phases of the AC signal in concert along the transmission lines. For the ring-based voltage controlled oscillators, each of the first and second transmission lines has an odd number of discrete elements.
