ABSTRACT:
In one aspect, the present invention includes a voltage controlled oscillator comprising an active device having a plurality of resonators coupled across two terminals of the device and at least one resonator coupled across the plurality of resonators. The at least one resonator preferably operates as an evanescent mode buffer capable of storing a select amount of energy present in the oscillator.
