Abstract
An apparatus configured to transmit and receive a radio frequency (RF) signal is provided. The apparatus includes a digital-to-analog converter (DAC) configured to convert a digital signal into an analog signal, a power amplifier configured to amplify the analog signal, and an antenna configured to output, as the RF signal, the amplified analog signal to the outside. The DAC includes a current cell matrix including a plurality of current cells configured to generate the analog signal, a plurality of normal paths configured to control the plurality of current cells to be turned on or off, based on the digital signal, and a plurality of alternative paths configured to selectively consume power, based on a pattern of the digital signal.
