Operational amplifiers ideal properties

We will now run a circuit with three ideal operational amplifiers. With the Lite version, the component limitation of PSpice limits us to two or three non-ideal operational amplifiers, depending on the complexity of the op-amp model. You may not be able to simulate the circuit of this section depending on the op-amp model you use. The ideal operational amplifier model was created so that a circuit with several operational amplifiers could be simulated using the Lite version. Simulation with ideal op-amps will give you a good idea about what the circuit is supposed to do, but it will not simulate any of the non-ideal properties that may cause your circuit to function improperly, or not meet certain specifications. Always use the non-ideal models when possible. For circuits with lots of op-amps, you will need the professional version of PSpice to accurately simulate the circuit if you want to include the non-ideal properties. Wire the circuit shown below. 

Many of the limitations and design criteria associated with real devices arise because of the failure of the operational amplifier to meet fully these ideal properties.
