Sigma-Delta Modulators: Tutorial Overview, Design Guide, and State-of-the-Art Survey 이전 글 : https://brush-up.tistory.com/306 SECTION IV.Nonideal Performance and Systematic Design더보기In previous sections, ΣΔMs have been considered ideal systems except for their inherent quantization error. In practice, such an ideal performance is degraded as a consequence of the circuit error mechanisms.14 Ther..

Sigma-Delta Modulators 의 기본 구조에 대해 학습하기 전에 일반적인 ADC의 과정에 대하여 알아보자 1. 일반적인 ADC 과정 이 과정에서 low pass 신호를 디지털화한다고 가정하자. LP 신호 외에 다른 신호를 사용할경우 base band 대역으로 옮기는 과정이 필요하기 때문에 LP 신호를 사용하여 해당과정은 생략할 수 있도록 한다. 아래 [그림1]과 같이 일반적인
