What is the gain of stage 1 and stage 2? What is the input impedance of stage 1

Question

What is the gain of stage 1 and stage 2? What is the input impedance of stage 1 and stage 2? What is the maximum voltage swing of stage 1 and stage 2? What is the 3db break point and full power bandwidth of stage 1? What is the 3db break point of stage 2? Assume that the slew rate degrades as the ratio of the voltage swing of this stage to the maximum found for stage 1, what is the full-power bandwidth of stage 2? What is the overall gain and bandwidth? Will this amplifier produce an output free of severe distortion? Explain.

Explanation / Answer

1) First stage is noninverting amplifier.

So Gain of the first stage=1+(Rf/R1)=1+(9K/1K)=10

Second stage is also noninverting amplifier.

So Gain of the second stage=1+(Rf/R1)=1+(infinite/infinite).

cannot say

2) Input impedance of stage 1=10K||5K=50/15=3.33K

Input impedance of stage 2=5K

3) Maximum voltage swing of stage 1 & stage 2 = +15V or -15V
