Abstract
A variable capacitor device is disclosed in which the capacitive tuning ratio and quality factor are increased to very high levels, and in which the capacitance value of the device is tuned and held to a desired value with a high level of accuracy and precision using a laser micromachining tuning process on suitably designed and fabricated capacitor devices. The tuning of the variable capacitor devices can be performed open-loop or closed-loop, depending on the precision of the eventual capacitor value needed or desired. Furthermore, the tuning to a pre-determined value can be performed before the variable capacitor device is connected to a circuit, or alternatively, the tuning to a desired value can be performed after the variable capacitor device has been connected into a circuit.
