Key Concepts

Input Current or Bias Current

For an ideal op amp, the input currents at both the inverting and non-inverting terminals are assumed to be zero. This assumption ensures that the op amp does not load the previous circuit stages, thus preserving the integrity of the signal being amplified. It simplifies the analysis by removing any consideration of biasing currents.

Voltage Gain in an Ideal Op Amp

In an ideal op amp, the voltage gain is assumed to be infinite. This means that any non-zero difference between the inverting and non-inverting inputs would, in theory, be amplified to an unlimited voltage level. This assumption is key in simplifying circuit analysis and designing feedback networks, as it leads to the concept that the voltage difference between the inputs is effectively zero in a closed-loop configuration.

Input Impedance or Resistance Between Terminals

An ideal op amp is characterized by infinite input impedance, meaning that no current flows between the input terminals. This property prevents the op amp from interfering with the circuit it is monitoring. The assumption of infinite resistance between the input terminals is crucial in ensuring that the connected circuit is not affected by the amplifier's presence.
