Operation Amplifiers (Op Amps)


Find the gain for the following circuit.

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.


Find the gain for the following circuit.

Noninverting Amplifier circuit


Find the gain for the following circuit.

Summing amplifier circuit


Find the gain for the following circuit.

Integrator circuit


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

Equation FormIf 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).

 

 


Write the node-voltage equations in phasor domain (jw) for the circuit shown below using the labels shown, incorporating the ideal op-amp model so that the equations are solvable, but do not solve.
