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 Webare identified in specifying the amplifier as input offset voltage and input bias current. The input offset voltage is fixed for a particular amplifier, however the contribution due to input bias current is dependent on the circuit configuration used.
