Capacitively-Coupled Chopper Operational Amplifiers

Research output: Chapter in Book/Conference proceedings/Edited volumeChapterScientific


In Chap. 3, the basic capacitively-coupled chopper topology for operational amplifiers (opamp) has been described. In this chapter, two capacitively-coupled chopper opamps (CCOPA) will be presented. They both achieve wide input common-mode voltage range (CMVR) and high precision. The first opamp employs a single-path architecture and features high power efficiency and simplicity. The second opamp is more complex and employs a multipath architecture. Thus, it is less power efficient, but has a wider bandwidth and a smoother transfer function.
