Demystifying Auto-Zero Amplifiers—Part 1：Whenever the subject of auto-zero or chopper-stabilized amplifiers comes up, the inevitable first question is “How do they really work?” Beyond curiosity about the devices’ inner workings, the real question in most engineers’ minds is, perhaps, “The dc precision looks incredible, but what kind of weird behavior am I going to have to live with if I use one of these in my circuit; and how can I design around the problems?” Part 1 of this article will attempt to answer both questions. In Part 2, to appear in the next issue, some very popular and timely applications will be mentioned to illustrate the significant advantages, as well as some of the drawbacks, of these parts.
