WebIn the next tutorial about Operational Amplifier basics, we will use negative feedback connected around the op-amp to produce a standard closed-loop amplifier circuit called an Inverting Amplifier circuit that produces an output signal which is 180 o “out-of-phase” with the input. Next Inverting Operational Amplifier WebA malfunctional ac-coupled op-amp circuit. What actually happens is that the input bias currents will flow through the coupling capacitor, charging it, until the common-mode voltage rating of the amplifier’s input circuit is exceeded or the output is driven into limits.
