Practice Questions

Question 1

What does the gain-bandwidth product (GBW) of an op-amp represent?

Question 2

In a non-inverting amplifier with closed-loop gain $A_{cl}=20$ and GBW = 1 MHz, what is its approximate bandwidth $f_c$?

Question 3

How is the slew rate (SR) of an op-amp defined?

Question 4

For a required sinusoidal output of 10 V peak, an op-amp has SR = 0.5 V/μs. What is the maximum frequency $f_{max}$ it can support without slew-rate distortion?

Question 5

A difference amplifier is built with $R_1=R_3=10\,\mathrm{k\Omega}$ and $R_2=R_4=40\,\mathrm{k\Omega}$. What is $V_{out}$ for $V_1=1\,$V at the inverting input and $V_2=3\,$V at the non-inverting input?
