View Patent ↗An embodiment of the present invention provides a capacitor, including a solid electrode, an electrode broken into subsections with a signal bus lines connecting the subsections; and wherein the signal bus further connects the solid electrode with the electrode broken into subsections.
1. An apparatus, comprising:
a capacitor including a solid electrode; and
an electrode broken into subsections with signal bus lines connecting said subsections such that the length of a signal path stays the same while an effective width increases thereby creating a reduction in resistance, leading to an increase in Q;
wherein said broken electrode is constructed of a lower resistance metal than said solid electrode and wherein a voltage tunable dielectric material is between said electrodes; and
wherein the voltage tunable dielectric material is a series network of voltage tunable dielectric capacitors which are all tuned using a common tuning voltage.
2. The apparatus of claim 1 , wherein said solid electrode and said broken electrode are adapted to reduce the mechanical stresses generated in metals and dielectric films of said capacitor.
3. The apparatus of claim 1 , wherein said subsections form a diamond shape.
4. The apparatus of claim 1 , wherein said subsections form a plurality of adjacent rectangular shapes.
5. A capacitor, comprising:
a solid electrode;
an electrode broken into subsections with signal bus lines connecting said subsections such that the length of a signal path stays the same while an effective width increases thereby creating a reduction in resistance, leading to an increase in Q;
wherein said broken electrode is constructed of a lower resistance metal than said solid electrode and wherein a voltage tunable dielectric material is between said electrodes;
said capacitor is in a pair of series capacitors and wherein said subsections are arranged in such a manner that it increases the effective width of the signal path in said solid electrode; and
