System and method for optimizing power supplies in a wireless transceiver
First Claim
1. A method comprising:
- determining a power requirement of one or more first tasks in a wireless transceiver;
selecting a first power supply to power the one or more first tasks based on the power requirement of the one or more first tasks;
determining a power requirement of one or more second tasks in the wireless transceiver;
selecting a second power supply to power the one or more second tasks based on the power requirement of the one or more second tasks;
determining a change in the power requirement of the one or more first tasks; and
selecting the first and second power supplies to power the one or more first tasks based on the change in the power requirement.

Abstract
Different components in a wireless transceiver are powered using different power supplies. For example, one or more first tasks in the wireless transceiver can be powered with a Galvanic cell, and one or more second tasks in the wireless transceiver can be powered with a fuel cell. The one or more first tasks could represent higher-current or intermittent tasks, and the one or more second tasks could represent lower-current or continuous tasks. The one or more first tasks could include transmission of a radio frequency (RF) signal, which may involve RF signal modulation or RF signal amplification. The one or more second tasks could include RF signal tuning, RF signal reception, RF signal demodulation, analog-to-digital conversion, digital-to-analog conversion, digital signal processing, operation of a controller, illumination of a display, operation of an audio speaker, operation of a microphone, or operation of a keypad.

11. An apparatus comprising:
-
a transmitter; a receiver; a first power supply; a second power supply; a multiplexer coupled to the transmitter, the receiver, and the first and second power supplies, the multiplexer operable to selectively couple the power supplies to the transmitter and receiver; and a controller operable to; determine a power requirement for each of the transmitter and the receiver; control the selective coupling of the power supplies to the transmitter and the receiver based on the power requirements of the transmitter and receiver; determine a change in the power requirement of at least one of the transmitter and the receiver; and adjust the selective coupling of the power supplies to the at least one of the transmitter and the receiver based on the change in the power requirement. - View Dependent Claims (12, 13, 14, 15, 16, 17, 18)

19. A computer readable medium embodying a computer program, the computer program comprising:
-
computer readable program code for determining a power requirement for each of multiple loads; computer readable program code for selecting multiple connections between multiple power supplies and the multiple loads, the connections selected based on power levels of at least some of the power supplies and the power requirements of at least some of the loads; computer readable program code for determining a change in the power requirement for at least one of the multiple loads; computer readable program code for changing at least one of the connections between at least one of the power supplies and the at least one load based on the change in the power requirement; and computer readable program code for initiating formation of and changing the connections. - View Dependent Claims (20)
