Abstract
Exemplary embodiments are directed to devices and methods for sharing an energy storage element within an electronic device. A device may include a plurality of transmit paths. The device may further include a voltage supply including an energy storage element coupled to each transmit path of the plurality of transmit paths.
Claims25
A device, comprising:
- a plurality of transmit paths;
- and
- a voltage source including a power converter and an energy storage element coupled to and shared by each transmit path of the plurality of transmit paths, the power converter configured to supply average current required by the plurality of transmit paths and the energy storage element configured to supply peak current required by the plurality of transmit paths.
A device, comprising:
- a first power amplifier;
- at least a second power amplifier;
- and
- a voltage supply including a power converter and an electric double-layer capacitor (EDLC) and configured for simultaneously supplying a voltage to each of the first power amplifier and the at least a second power amplifier, the power converter configured to supply average current required by the power amplifiers and the EDLC configured to supply peak current required by the power amplifiers.
