Abstract
A programmable capacitive network for use in a tunable resonant circuit is set forth that may be used in a number of different applications, but is particularly useful in the tuning of a voltage controlled oscillator formed on a substrate, such as a semiconductor substrate or the like. The programmable capacitive network includes a plurality of capacitive elements. An interconnected network of voltage gate elements and fuse elements are interconnected with the capacitive elements to selectively connect one or more of the plurality of capacitive elements in the resonant circuit in response to at least one program control signal. In accordance with one embodiment, the voltage gate elements are diodes.
