Inverting Op-Amp

In this lab we had to use an op-amp and resistors to create a gain of 2
Here's our circuit



























We used a 20k resistor as our Rin, and 10k for our Rout.The actual values for both resistors are 19.91k Ohm and 9.94k Ohm, respectively. We used an analog discovery to produce +5 and -5 volts to the opamp, and then provided the varied Vin voltage also using the analog discovery. As we changed the Vin voltage we noticed that -3V to -2.0 V was the voltage necessary to obtain a Vout saturation of 4.29. When we  changed our Vin to -1.5 V we noticed that our Vout stopped being saturated. We then began to increase the Vin until we reached a negetive saturation at 2.0 V. Once we had a Vin of 2.0 V our Vout was saturated at -3.5 V. Looking at our values we noticed that we obtained a gain of 2 when our Vin ranged from -1.5 to 1.5. So basically I noticed that we obtain the gain we want in the linear part of our graph

Here's the data I plotted

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...
