Question

The op amp in the noninverting amplifier circuit shown has an input resistance of 400 kΩ, an output resistance of 5 kΩ, and an open-loop gain of 20,000. Assume that the op amp is operating in its linear region.

1. Calculate the voltage gain (vo/vg).

2. Find the inverting and noninverting input voltages vn and vp (in millivolts) if vg=1 V.

3. Calculate the difference (vp-vn) in microvolts when vg=1 V.

4. Find the current drain in picoamperes on the signal source vg when vg=1 V.

5. Repeat (a)–(d) assuming an ideal op amp.
