4/4 inverting Voltage Amplifier

    The purpose of this lab is to verify the function of inverting voltage amplifier. The inverting voltage amplifier will change the sign of input voltage. If the input voltage is positive, then the output voltage will be negative.

1. Provide a schematic of the circuit you designed, including actual resistance values used in your circuit.

This is the circuit we designed for this lab. The actual resistors we used in this lab are 2.2K and 4.7K

2. Attach a table of output and input voltages for your circuit. Also attach a plot of the output vs. input voltage.

3. Provide a brief discussion on your results and a comparison between measured and expected circuit gain. 

The relationship between Vout and Vin is Vout = -(R2/R1)*Vin

which is agree with our graph table.

Summary 

       In today's class, we learned the concept of inverting and non- inverting amplifier. The invert amplifier will change the sign of output voltage with the input voltage. However, the non-inverting will not change the sign of output voltage.
