  • AC Coupling Instrumentation and Difference Amplifiers

    2011-8-6 · AC coupling to an instrumentation ampli-fier (IA) or difference amplifier can be used to accurately extract the AC signal while rejecting DC and common-mode noise. Adding capacitors and resistors to AC couple the inputs of an instrumentation amplifier or difference amplifier seems like an obvious approach for AC coupling, but it has prob-lems.

  • Advantages of AC-Coupling in SerDes Applications |

    AC-coupled circuits remove any signal below some frequency threshold. Look back at the figure: what is the frequency of the DC signal? It’s pretty low, or even zero -- as in, it’s not moving. That means that the AC-coupled circuit will filter it out completely. Does this sound like any familiar utility?
