Abstract:
An apparatus and method for controlling Transmit (Tx) power when a portable terminal performs human body communication with a counterpart portable device are provided. The apparatus includes a voltage manager for determining whether the Tx power needs to be changed based on an output voltage that is based on a current that varies according to a distance between an electrode of a portable terminal and an electrode of a counterpart portable terminal, and changes the Tx power according to a result of the determination.
