Abstract

본 발명은 저항 분배기와 OP앰프를 이용한 저전력 고해상도를 실현한 디지탈/아날로그 컨버터에 관한 것으로서 본 발명에 따른 8비트의 새그먼트 방식의 디지탈/아날로그 컨버터를 포함하여 구성한 디지탈/아날로그 컨버터는 상기 8비트 새그먼트 방식의 디지탈/아날로그 컨버터의 상위 신호비트 스위치와 하위 신호비트 스위치로부터 출력된 아날로그 전류와 추가된 4비트의 하위 신호 비트의 스위치로부터 출력된 아날로그 전류를 1/16로 스케일 다운시킨 전류를 합하여 이득이 큰 OP앰프단을 거쳐 고해상도의 아날로그 신호를 출력시키는 것을 특징으로 한다.The present invention relates to a digital / analog converter that realizes low power and high resolution using a resistor divider and an op amp. Gain by adding the current scaled down to 1/16 by the analog current output from the upper signal bit switch and the lower signal bit switch of the digital-to-analog converter with the additional 4-bit lower signal bit. It is characterized by outputting a high resolution analog signal via this large OP amplifier stage.

따라서 상술한 바와 같이 본 발명에 따른 디지탈/아날로그 컨버터는 고해상도를 실현하고 고해상도를 실현함에 따라 칩크기의 문제와 소비전력이 증가하는 문제를 해결하는 효과를 갖는다.Therefore, as described above, the digital-to-analog converter according to the present invention has the effect of solving the problem of chip size and power consumption increase as the high resolution is realized.
