Can An Op-Amp Perfectly Reject Common-Mode Signals?

Описание: Ever wondered about the ideal capabilities of an operational amplifier? This video delves into a fundamental question in analog circuit design: can an op-amp truly achieve perfect common-mode signal rejection? Join us as we explore the theoretical limits and practical considerations of this crucial characteristic.

Key takeaways from this essential discussion include:
► Understanding the theoretical basis of common-mode rejection in ideal op-amps.
► Exploring the concept of Common-Mode Rejection Ratio (CMRR) and its significance in real-world applications.
► Identifying factors that limit an op-amp's ability to perfectly reject common-mode signals, such as device mismatches.
► Discovering practical circuit design techniques to maximize CMRR in amplifier stages.
► Analyzing the impact of common-mode signals on precision measurements and instrumentation.
