Abstract
A device for controlling voltage in a power amplifier of a portable wireless terminal according to the present invention, includes a power amplifier adapted to adjust an amplification degree of a signal inputted in response to a supply state of a reference voltage to output the adjusted signal. The device also includes a comparator/limiter adapted to compare a value of a transmitting automatic gain controlled (TX_AGC) supply voltage and a value of an operating supply voltage to output the compared result and a power supply conversion section adapted to convert a state of the compared result outputted from the comparator/limiter into a reference voltage state for application to the power amplifier as a reference voltage thereof.
