According to an example embodiment, an apparatus is provided that produces a small-step switchable
capacitor, which can have steps that are smaller in value than the smallest
capacitor used in the
system. In one embodiment, an input
signal is connected to a switchable
capacitor system that includes at least one and / or a plurality of small-step, switchable capacitors. In an example embodiment, a capacitor
system may be provided that includes a first
capacitance block coupled in series with a second
capacitance block. In an example embodiment, the second
capacitance block may include one or more switchable capacitors to provide a step in capacitance for the capacitor system between a first setting and a second setting using the one or more switchable capacitors. Also, in an example embodiment, the step in capacitance of the capacitor system may be determined based, at least in part, on a ratio of the capacitance of the second capacitance block to the capacitance of the first capacitance block.
