Expert Solution

Step 1: Summarize the details given:

Given Data:

The characteristics of 2 Op-Amps as,

Op-Amp	$Z subscript i n end subscript$	$Z subscript o u t end subscript$	$A subscript o l end subscript$
1	$5 space text MΩ end text$	$100 space text Ω end text$	$50000$
2	$10 space text MΩ end text$	$75 space text Ω end text$	$150 comma 000$

2. An Op-Amp with,

Common Mode Rejection Ratio $C M R R equals 300 comma 000$
Open Loop gain $A subscript o l end subscript equals 90 comma 000$

3. An Op-Amp with,

Voltage range $open parentheses V subscript 1 comma V subscript 2 close parentheses equals open parentheses negative 10 comma space 10 close parentheses space text V end text$
Slew rate $S R equals 0.5 bevelled fraction numerator space text V end text over denominator text μs end text end fraction$

4. An Op-amp circuit with,

Input resistance $R subscript i equals 2.2 space text kΩ end text$
Feedback resistance $R subscript f equals 22 space text kΩ end text$

To Find:

Desirable Op-amp.
Common mode gain.
The time to reach $V subscript 2$ form $V subscript 1$ .
The values of $A subscript V comma space V subscript o u t end subscript comma space I subscript i n space end subscript & space I subscript f$ .
