Question

a) Degine the inverting amplifier for a nominal gain of 4, a gain error of
0.1%, and an input Impedance of at least 10 k.
b) A noninverting amplifier incorporates an op amp having a gain of 100.
Determine the gain error if the circuit is to provide a nominal gain of s.​

Answer 1

Answer:

The widely used 741 op-amp has a typical open loop gain of 200,000 V/V. With the 741 used in an inverting amplifier circuit, the error
