non-inverting amp

The relationship for the non-inverting voltage amplifier was

Vout=Vin*(  (R2/R1)+1)

Our resistors values were 20k Ohms for the second resistor, but an actual resistance of 21.2k Ohm. For the first resistor the value is 10k Ohm, and the actual value is 9.95k Ohm.

For the procedure, we increased the Vin voltage and wrote down the Vout voltage and created a graph.
Here's the circuit diagram






Here is our circuit

Here are our values
 
We noticed that we reached saturation at -3.51 and 4.28 for the Vout. From our calculation we were supposed to have a gain of around 3. We only achieved this when our Vin went from -1.5 to 1.0 V. After that our values began to not match our theoretical gain. So from this we can deduce to achieve peak gain we need to stay between -1.5 and 1.0 volts.

Summing Amp Lab

Image
For this lab we had to design an inverting summing circuit. Our two input resistors, R1 and R2 had resistances of 21.2 Kohm and 21.6 Kohm respectively. Theoretically they should R1=22k and R2=22k. Our output resistor had an theoretical resistance of 10k and an actual resistance of 9.7 k. For this lab we had to keep V1 at 1 V, change the Vb voltage and then measure the output voltage. For the second trial, we had to keep V2 at 1 v, change Va and measure the output voltage again. For our prelab, we calculated that our out resistor voltage should be Vo=-(Va+Vb)(R3/R1) Here's the circuit diagram Heres a picture of our circuit Here's our values for constant Va at 1 V Va=1 vb vo -4 1.38 -2 0.46 -1 0 0 -0.42 1 -0.88 2 -1.35 3 -1.81 5 -2.73  Here's our graph We noticed that the op-amp reached saturation at 1.38V and -2.73 V Here...

Inductor Voltage-Current Relations

Image
For this lab we had a resistor and an inductor in series. We had to measure voltages for both elements and use this information to calculate the current running through inductor. The way we could see if our data was accurate was to use Ohm's law through the resistor. Since both elements are in series the would have the same current. For this lab we had a 1mH inductor a 17.6 ohm resistor. Here's a picture of our circuit Here's our graph window for a sinusoidal input voltage with frequency = 1kHz, amplitude = 2V, and offset = 0V Here's our graph window for a  sinusoidal input voltage with frequency = 2 kHz, amplitude = 2V, and offset = 0V Here's the inductor current we got from the wavegen generator and the one calculated from the pre-lab. Our values are pretty off, and I'm not exactly sure why, I'm assuming our math equation was wrong. Here's the graph When we had a frequency of 2khz we basically got the same graph, I'm assuming ...

Lab Day one

Image
Lab day 1 On the first day of lab I did the solderless breadboard lab and another lab that was assigned from the board. Here's the solderless breadboard lab Solderless Breadboards This is the resistance i got when i connected the leads of the DMM to two holes in the same row. The value is .8 ohms which is really low. This operates as a short circuit.  When we connected the two rows of hole son opposite sides of the central channel we noticed that we had a really high resistance, this is because the leads are separated from each other which causes an open circuit. When we connected the leads in two arbitrary holes our DMM had a very large resistance, this is because again, the leads are isolated which causes an open circuit When we connected the leads with a jumper wire between the nodes our DMM read a very low resistance. The reason for this is because this configuration causes a short circuit. For the first part of the lab w...
