Abstract
The present disclosure may include, for example, a tunable capacitor having a decoder for generating a plurality of control signals, and an array of tunable switched capacitors comprising a plurality of fixed capacitors coupled to a plurality of switches. The plurality of switches can be controlled by the plurality of control signals to manage a tunable range of reactance of the array of tunable switched capacitors. Additionally, the array of tunable switched capacitors is adapted to have non-uniform quality (Q) factors. Additional embodiments are disclosed.
Claims20
A device comprising:
- a plurality of reactive elements on a single die, wherein the single die has a plurality of ports coupled to the plurality of reactive elements;
- a switching system comprising a group of switches, wherein the switching system is coupled with the plurality of reactive elements, the plurality of reactive elements thereby configurable to any of a plurality of topologies according to switch positions of the group of switches;
- and
- a decoder coupled to the switching system for generating decoded signals to selectively enable and disable the plurality of reactive elements,
- wherein the plurality of reactive elements, the switching system and the decoder form a variable matching network, and wherein the decoder receives a control signal for tuning the variable matching network with respect to a performance parameter of the device.
