Understanding Op Amp Parameters-Chapter 11Bruce Carter
None of the above-given parameters can be practically realized. A practical or real op-amp has some unavoidable imperfections and hence its characteristics differ from the ideal one. A real op-amp will have non-zero and non-infinite parameters. ...

The equivalent circuit of an op-amp is the circuit where the op-amp parameters are represented in terms of physical components. Such a representation is very helpful for analysis purposes. Below, you can find the equivalent circuit of theop amp. ...
The key parameters of the op amp are its input voltage and current noise, bias current, unity gain-bandwidth product, fu, and input capacitance, Cin. The HP 5082-4204 PIN Photodiode will be used as an example for our discussion. Its characteristics are given in Figure 2.61. It is ...
negligibly large compared with the input impedance of the preceding circuit, and the output impedance is negligibly small compared with the impedance of the subsequent load. Therefore, these impedances usually do not have a significant impact. The same is true of the other param...
