Hello,

What type of components are you allowed to use to make these circuits?

For example, resistors, capacitors, op amps, etc. ?
This is necessary to know beforehand. You might get this info from previous questions in the coursework.

Also, do you know what a voltage divider is?
Or an amplifier?

E12 series components
Resistors
op amp

 

Here is a link to a help you learn about op-amps. Use the non-inverting half of the link.
amp gain calculator
Here is a picture of a non inverting amplifier. The wire going up goes to +5 volts and the one going down goes to -5 volts.

The calculator works like this: Fill in Rin and Rf then hit Calculate.

Do you have anything like this in your book?

Please see what i have design without any help. I am happy to share all the pages on which i worked as well.

What does this have to do with the problem you're trying to solve? You drew a non-inverting amplifier with a gain of 3 2. That circuit is available in just about any opamp datasheet.
EDIT: corrected gain.

It would be helpful if you put parameters for V1 on the schematic.

This is the more typical way to draw that circuit. From Signetics:

What does this have to do with the problem you're trying to solve? You drew a non-inverting amplifier with a gain of 3. That circuit is available in just about any opamp datasheet.

Could you please guide me a little what step i should do next. Do I have to add value to Vi and Vout ?

Good Job. You have a gain of 2. (not 3. @dl324)
Input voltage = 0.2 output voltage 2.2. What gain do you need? What resistors to get that gain?

 

(not 3. @dl324)

My bad. Too early in the morning. Gain is \(1+\frac{R2}{R1} = 2\)

I think i will need two resistors each of 10

You've already been given a link to a calculator; or you could do the arithmetic yourself. What gain do you need for each amplifier and what are you going to do about the DC offset of the input signal?

Thank you

10 what? Ohms, k ohms, M ohms, ...

As we've established, that will give you a gain of 2. How much gain do you need for each amplifier?

what will be the correct value of E12 series resistors please?

kohm

 

what will be the correct value of E12 series resistors please?

What gain do you need to amplify 0.2V p-p to 2.2V p-p? If you subtract 1 from that, what does the ratio of the two resistors need to be?

When is this problem due? You've already spent days on a problem that shouldn't take more than a minute or two.

Thanks, but i still have not completely get it. Do i need to take resistors each of 1 KOhms?

Take it in steps.

Is my Schematic wrong?

 

2

What is 2.2 / 2 0.2?
EDIT: corrected typo.

Is my Schematic wrong?

Not wrong, just drawn unconventionally. If you draw circuits the "usual" way, intent can be seen at a glance.

Thanks Dennis. I will do it again and will add values as well.

 

What is 2.2 / 2?

????
input is 0.2V and output is 2.2.
2.2/0.2 =?
0.2V x gain = 2.2 volts (solve for gain)
