Operation Amplifiers (Op Amps)

For each of the circuits shown below, find the gain. Gain is defined as the ratio of the output to the input, i.e., Vout/Vin.

Inverting Amplifier Circuit. Vin on the left connected to R1 connected to the negative terminal of the opamp connected to R2 connected to Vout and the output of the opamp. Positive terminal of the opamp tied to ground.

Solution

This circuit is an active filter. Solve for the gain and then arrange your answer in the following form:

Equation Form If you can get this form, you have a low pass filter, where Ho is the DC gain and Wo is the corner frequency (they should both be constants that depend on the component values in the circuit).
