Abstract
A method for use in an electronic device having an amplification unit, the method comprising: detecting a current temperature of the electronic device when the amplification unit is in a first state in which the amplification unit is operated in accordance with first control value; detecting whether the current temperature meets a threshold; identifying a second control value that is lower than the first control value, when the current temperature meets the threshold; and changing an amount of power supplied to the amplification unit by transitioning the amplification unit into a second state in which the amplification unit is operated in accordance with the second control value.

A method for use in an electronic device having an amplification unit, the method comprising:
- detecting a current temperature of the electronic device when the amplification unit is in a first state in which the amplification unit is operated in accordance with a first control value;
- detecting whether the current temperature exceeds a threshold;
- identifying a second control value that is designated for improving a current consumption according to heating in the electronic device when the current temperature exceeds the threshold, wherein the first and second control values are set to output same target power, wherein the second control value is lower than the first control value, and wherein power consumption corresponding to the first control value is higher than power consumption corresponding to the second control value;
- and
- changing an amount of power used by the amplification unit by transitioning the amplification unit into a second state in which the amplification unit is operated in accordance with the second control value,
- wherein the first control value is selected based on a first lookup table that is used to operate the amplification unit when the current temperature of the electronic device fails to exceed the threshold, and
- wherein the second control value is selected based on a second lookup table that is used to operate the amplification unit when the current temperature of the electronic device exceeds the threshold.
An apparatus comprising:
- a temperature sensing unit;
- an amplification unit;
- and
- at least one processor configured to:
- detect, by the temperature sensing unit, a current temperature of the apparatus when the amplification unit is in a first state in which the amplification unit is operated in accordance with a first control value;
- detect whether the current temperature exceeds a threshold;
- identify a second control value that is designated for improving a current consumption according to heating in the apparatus when the current temperature exceeds the threshold, wherein the first and second control values are set to output same target power, wherein the second control value is lower than the first control value, and wherein power consumption corresponding to the first control value is higher than power consumption corresponding to the second control value;
- and
- change an amount of power used by the amplification unit by transitioning the amplification unit into a second state in which the amplification unit is operated in accordance with the second control value,
- wherein the first control value is selected based on a first lookup table, and the first lookup table is used to operate the amplification unit when the current temperature of the apparatus fails to exceed the threshold, and
- wherein the second control value is selected based on a second lookup table, and the second lookup table is used to operate the amplification unit when the current temperature of the apparatus exceeds the threshold.
