Abstract
A power generation technique to generate power for use in, for instance, a communication device having a transmitter and a receiver, where communication occurs over atmosphere, or airways (e.g., wireless). The present invention provides a battery-based system that generates power at a high current and high voltage while accommodating the required duty cycles using batteries with sizes that are not prohibitive given the size constraints associated with portable devices in general.

10. An apparatus for generating power for use in a electronic device, said apparatus comprising:
-
a first battery to supply power at a first voltage and a first current; a second battery to supply power at a second voltage and second current, wherein the second current and power from the second battery are greater than the first current and power from the first battery respectively; and a charging mechanism coupled to the first battery and the second battery, wherein the charging mechanism comprises an upconverter to convert the first voltage to a third voltage large enough to charge the second battery and a controller that monitors the second voltage of the second battery and controls flow of current between the first battery and the second battery, wherein the controller causes current to flow from the first battery to the second battery to charge the second battery when the second battery voltage is below a first level and stops the flow of current between the first battery and the second battery when the second battery has been charged to a predetermined level. - View Dependent Claims (11, 12, 13, 14)
