Inverting Voltage Amplifier

In today's lab, we will be concerned with the steady-state response of an inverting voltage amplifier to sinusoidal inputs.

 At f = 100, 1000, and 5000 we calculated the gains and angles for the output.

This is how the circuit is connected.

This is the input/output data at f = 100

The angle is 27.7 and the gain is 0.87

This is the input/output data at f = 1000

The angle is 79.2 and the gain is 0.191

This is the input/output data at f = 5000

The angle is 90 and the gain is 0.05

As the frequency increases, the angle increases, and the gain decreases.
