Question 7
For an op-amp amplifier circuit has a closed-loop voltagegain of 5. If the op-amp used has a gain-bandwidth productof 1.5 MHz, and we can only tolerate 10% drop in gain, whatwill be the maximum usable frequency? (help me do this question with explanation)
1. Find vo in the circuit shown if va=0.1 V and vb=0.25 V.
2. If vb=0.25 V, how large can va be before the op amp saturates?
3. If va=0.10 V, how large can vb be before the op amp saturates?
4. Repeat (a), (b), and (c) with the polarity of vb reversed?
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.
