Abstract:
1. A method of adjusting the resulting capacitance value of a thin film capacitor while such capacitor is in operation in a circuit, comprising: providing a capacitor having respective first and second terminals; and providing a capacitor array, situated electrically between such respective first and second terminals, such capacitor array comprising a plurality of respectively valued sub-component capacitors, arranged so that respective of such sub-component capacitors may be removed from the resulting capacitance value of such adjustable thin film capacitor; and adjusting the resulting capacitance value of such thin film capacitor by respectively removing therefrom selected of such respectively valued sub-component capacitors; wherein such sub-component capacitors comprise a base value capacitor and plural parallel coupled capacitors configured such that one or more of the parallel coupled capacitors may be effectively removed from such parallel connection; such plural parallel coupled capacitors are coupled by way of fusible links, configured in a capacitive laddering effect; and such adjusting step includes adjusting the resulting capacitance value of such thin film capacitor by selectively removing one or more of such parallel coupled capacitors from such parallel connection thereof by disrupting their corresponding fusible links, so as to correspondingly adjust the resulting capacitance value of such thin film capacitor.
