다치논리를 적용한 D/A변환기의 설계

초록

In this paper, we designed 12bit DAC(Digital to Analog Converter) that applied to multiple-valued logic system to binary system. The proposed D/A Converter structure consists of the Binary to Quaternary Converter(BQC) and Quaternary to Analog Converter(QAC). The BQC converts the two input binary signals to the one Digit Quaternary ouput signal. The QAC convets the Quaternary input signal to theAnalog output signal. the proposed DAC structure can implement voltage mode DAC that high resolution low power consumption with reduced chip area. And also, it has advantage of the easy expansion of resolution and fast settling time.
