Abstract
An oscillator comprises a resonator for providing an oscillation frequency for the oscillator, an active network, coupled to the resonator, for driving the resonator, and a split-ring resonator coupled to the main resonator and used to provide amplitude and phase balanced outputs. The split-ring resonator has at least a first edge, which is coupled to the resonator, and a second edge. The second edge has a gap therein, and a first terminal located at one side of the gap, and a second terminal symmetrically located at the other side of the gap.
