| 20110050337 | SUPPLY VOLTAGE CONTROL DEVICE FOR AMPLIFIER - A supply voltage control device for an amplifier that controls a supply voltage for the amplifier has been improved. The supply voltage control device includes: a supply voltage control circuit including an error amplification circuit that feeds an error current so as to control the supply voltage for the amplifier, and a direct current feed circuit that feeds a direct current (or the direct current and a current of a low-frequency component); a high-frequency component extraction unit that extracts a predetermined high-frequency component contained in a signal resulting from detection of an envelope relevant to a signal to be amplified by the amplifier; a peak hold unit that performs peak hold processing on a signal of the extracted high-frequency component; and an addition unit that adds up a signal based on the result of detection of the envelope relevant to the signal to be amplified by the amplifier, and the signal resulting from the peak hold processing, and inputs a signal resulting from the addition to the supply voltage control circuit. | 03-03-2011 |
