초핑 기술은 증폭기의 오프셋과 저주파 잡음을 스위칭 주파수까지 상향 변조하므로 낮은 오프셋과 낮은 온도 드리프트를 달성할 수 있습니다. 반면에 상향 변조된 리플 및 글리치와 같은 스위칭 아티팩트로 인해 원치 않는 AC 및 DC 오류가 발생합니다. 본 논문에서는 이러한 스위칭 아티팩트를 줄이는 다양한 회로 기술을 요약하고 각 기술의 장점과 단점을 논의합니다. 비교 결과에 따르면 고급 회로 기술을 사용하는 최신 설계는 더 높은 초핑 주파수로 더 낮은 DC 및 AC 오류를 달성할 수 있습니다.

Abstract: Chopping technique up-modulates amplifier's offset and low-frequency noise up to its switching frequency, and therefore can achieve low offset and low temperature drift. On the other hand, it generates unwanted AC and DC errors due to its switching artifacts such as up-modulated ripple and glitches. This paper summarizes various circuit techniques of reducing such switching artifacts, and then discusses the advantages and disadvantages of each technique. The comparison shows that newer designs with advanced circuit techniques can achieve lower DC and AC errors with higher chopping frequency.
