Abstract:
A method for minimizing power supplied to a transmitter of a battery-operated mobile unit by adaptively providing one of a first supply voltage or a second supply voltage to the transmitter, the method comprising the steps of:(a) determining an appropriate transmitter output level for transmitting data between the mobile unit and a base station; (b) determining an appropriate supply voltage to the transmitter, wherein the transmitter amplifies input signals at a first output level when the first supply voltage is applied to the transmitter, further wherein the transmitter amplifies input signals at a second output level when the second supply voltage is applied to the transmitter; (c) applying the first supply voltage to the transmitter when the appropriate supply voltage is the first supply voltage; (d) applying the second supply voltage to the transmitter when the appropriate supply voltage is the second supply voltage, wherein the second supply voltage is converted from the first supply voltage by a voltage converter; (e) activating a first transistor and deactivating a second transistor when the first supply voltage is applied; and (f) applying an oscillating pulse to the first transistor and applying an inverse of the oscillating pulse to the second transistor when the second supply voltage is applied.
