| description | The present invention provides a digital-to-analog converter (DAC) operating at a high frequency for generating a radio frequency (RF) signal and guaranteeing high linearity and a device including the same. According to an example embodiment of the present disclosure, the device transmits and receives a radio frequency (RF) signal and comprises: 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 the amplified analog signal as the RF signal to the outside. The DAC includes: a current cell matrix including a plurality of current cells for generating the analog signal; a plurality of general paths configured to control on/off of the plurality of current cells based on the digital signal; and a plurality of alternative paths configured to cause selective power consumption based on a pattern of the digital signal.
본 개시의 기술적 사상의 예시적 실시예에 따라 Radio Frequency) 신호를 송수신하는 장치는, 디지털 신호를 아날로그 신호로 변환하도록 구성된 디지털-아날로그 변환기(Digital to Analog Converter; 이하, DAC), 상기 아날로그 신호를 증폭하도록 구성된 전력 증폭기 및 증폭된 상기 아날로그 신호를 상기 RF 신호로서 외부로 출력하도록 구성된 안테나를 포함하며, 상기 DAC는, 상기 아날로그 신호를 생성하기 위한 복수의 전류 셀들을 포함하는 전류 셀 매트릭스, 상기 디지털 신호를 기반으로 상기 복수의 전류 셀들의 온/오프를 제어하도록 구성된 복수의 일반 경로들 및 상기 디지털 신호의 패턴을 기반으로 선택적인 전력 소모를 발생시키도록 구성된 복수의 대체 경로들을 포함하는 것을 특징으로 한다. |
