APPARATUS INCLUDING ELECTRONIC CIRCUIT FOR AMPLIFYING SIGNAL

The apparatus relates to a pre-5th-Generation (5G) or 5G communication system to be provided for supporting higher data rates Beyond 4th-Generation (4G) communication system such as Long-Term Evolution (LTE). The disclosure relates to an apparatus including an electronic circuit for amplifying a signal. The apparatus includes a transceiver including an amplification circuit, and at least one processor coupled to the transceiver. The amplification circuit includes a first path to generate a first current corresponding to a voltage of an input signal, a second path to generate a second current corresponding to a voltage of the input signal, a separation unit to control each of the first current and the second current, a current mirror to generate a third current corresponding to the first current, and a folding unit to generate an output signal on the basis of the second current and the third current.
