Abstract

The present invention applies to the field of energy saving, and in particular, to an apparatus, a method, and a mobile terminal for reducing power consumption on a power amplifier. In embodiments of the present invention, a controller is separately connected to a temperature detector and a voltage converter. The controller searches for, according to a temperature of the power amplifier detected by the temperature detector, a voltage compensation value corresponding to the temperature, and controls, according to the voltage compensation value, the voltage converter to output a power voltage that is capable of improving efficiency of the power amplifier. This may enable the power amplifier to work in an optimal efficiency at any temperature, and greatly reduce the power consumption of the power amplifier.

Description

technical field [0001] The invention belongs to the field of energy saving, and in particular relates to a power amplifier consumption reduction device, method and mobile terminal. Background technique [0002] Mobile terminal products have high requirements on power consumption. Reducing power consumption of battery-powered mobile terminals can increase its battery life. The power consumption of the power amplifier is the main power consumption part of the entire device, and it can account for 50% of the current popular 3G mobile phones. ,even more. Under the same output power and input power, the higher the efficiency of the power amplifier, the smaller its power consumption. Therefore, optimizing the efficiency of the power amplifier has a significant effect on reducing the power consumption of the whole machine. [0003] At present, the power amplifier uses the same power supply voltage at any ambient temperature, so that at room temperature and low temperature, its ope...
