Non-inverting op-amp exercise
Open this simulation model of a non-inverting amplifier.
What is the gain of this amplifier?
show answer
From the video, the gain expression for the non-inverting amplifier is,
$v_o = v_{in} \,\dfrac{\text R1 + \text R2}{\text R2}$
Fill in the resistor values,
$v_o = v_{in} \,\dfrac{5\,\text k + 10\,\text k}{10\,\text k}$
$v_o = v_{in} \,\dfrac{15}{10}$
$v_o = 1.5\,v_{in}$
The gain is $1.5$.
Click on TRAN to run a transient simulation.
Does the simulation match your gain calculation?
Design an amplifier with a gain of $2$.
Hint: Pick new values for either or both of $\text R1$ and $\text R2$.
Change the values of the resistors in the simulation and run TRAN again.
Verify your new amplifier has the gain you expect.
Starting from scratch with a blank schematic, design and simulate a non-inverting amplifier with a gain of $30$.
