Abstract:
(EN) An analog-to-digital conversion apparatus according to the present technology comprises: a first calculator for performing subtraction of an analog signal and an analog value; an amplifier for amplifying an output of the first calculator; a filter for filtering an output of the amplifier; a quantizer for generating a digital bit stream, on the basis of an output of the filter; and a digital-to-analog converter for outputting an analog value according to the digital bit stream.
(FR) Un appareil de conversion analogique-numérique selon la présente technologie comprend : un premier calculateur pour effectuer la soustraction d'un signal analogique et d'une valeur analogique ; un amplificateur pour amplifier une sortie du premier calculateur ; un filtre pour filtrer une sortie de l'amplificateur ; un quantificateur pour générer un train binaire numérique, sur la base d'une sortie du filtre ; et un convertisseur numérique-analogique pour délivrer en sortie une valeur analogique en fonction du train binaire numérique.
(KO) 본 기술에 의한 아날로그 디지털 변환 장치는 아날로그 신호와 아날로그 값을 뺄셈하는 제 1 연산기; 제 1 연산기의 출력을 증폭하는 증폭기; 증폭기의 출력을 필터링하는 필터; 필터의 출력으로부터 디지털 비트 스트림을 생성하는 양자화기; 및 디지털 비트 스트림에 따라 아날로그 값을 출력하는 디지털 아날로그 변환기를 포함한다.
