is the range of gain values expected from such a circuit? An inverting op amp circuit is fabricated with the resistors R, and R2 having x% tolerance (that is, the value of each resistance can deviate from the nominal value by as much as x%). What is the tolerance on the realized closed-loop gain? As- sume the op amp to be ideal. If the nominal closed-loop gain is -100 V/V and x = 5, what
If the open loop gain of an op-amp is very large, does the closed loop gain depend upon the external components or the op-amp? Explain the meaning of open loop and closed loop operation of an op- amp? What is a practical op-amp? Draw its equivalent circuit.
