Simplifying ideal op amps
Webb24 feb. 2012 · An operational amplifier (OP Amp) is a direct current coupled voltage amplifier. That is, it increases the input voltage that passes through it. The input resistance of an OP amp should be high whereas the output resistance should be low. An OP amp should also have very high open loop gain. WebbOp-amp model has many forms. According to analyzing accuracy, it can be divided into ideal op-amp model, nonideal op--amp model and opamp - macro model, etc. According …
