The gain is normally referred to as A in texts, so the equation for the output is given by:. Let's model a voltage-controlled voltage source and see if we can't get its behavior to mimic an ideal op amp. Op amps are not meant to be used as stand-alone devices. We simply verified the Vout equation in the ideal op amp video to show why it is commonly referred to as a voltage-controlled voltage source. We are going to talk about feedback and closed-loop gain and application.

What is feedback? Feedback occurs when the output of a system is fed back into as input s. There are two types of feedback: positive regenerative and negative degenerative. Feedback is applied to the system to affect one or more of the following properties:.

When were talking about gain, we are taking the ratio of the output to the input. In the. Here's the conversion formula. All of the feedback comes at a price, and that cost is the gain. Negative feedback trades gain for more desirable properties; increasing the input resistance also increases the bandwidth. Unlike open-loop gain, the closed-loop gain is dependent on the external circuitry because of the feedback.

However, it can be generalized. An example of an inverting configuration consists of one op amp and two resistors, R1 and R2. R2 is connected from the output terminal of the op amp to the inverting or minus terminal of the op amp. R2 closes the loop around the op amp. One thing not mentioned in the video below, but is considered implied because we are still using the ideal op amp, is that no current flows through the op amp.

All the current I1 flowing through R1 is also flowing through R2. This is known as the unity-gain inverter. A typical application for an inverting amplifier is a summing amplifier, also known as a virtual earth mixer, used in audio mixing.

I happen to have quite a few LM op amps lying around, so I went ahead and built a summing amplifier. First I modeled it in LTSpice. The voltage follower is a nice example of a non-inverting amplifier. The property of very high input impedance is a desirable feature of the non-inverting configuration. The voltage follower can used as a unity-gain buffer amplifier connected from a high impedance source to a low impedance source - this helps to avoid loading effects on the driving circuit.

Difference amplifiers respond to the difference between two signals applied at its input, and rejects signals that are common to the two inputs. By combining these two topologies we are getting closer to be able to design a circuit that will be able to obtain the difference between the two input signals.

In order to accomplish this, we must first make sure the gain magnitudes think absolute values that are always positive of each are equal. We now have four resistors; we need to make sure the gains are equal so the ratio of the resistors is important:. The problem with this circuit is that in order to obtain high gain, R1 must be relatively low.

This causes the input resistance to drop. Another issue is that it isn't easy to vary the gain of this amplifier. Both of these issues are solved with the implementation of the instrumentation amplifier. Using three op amps, we can get a fine-tuned differential amplifier.

Since we have the problem of low input resistance using one op amp, we can add an additional voltage follower or buffer at each input. Even more awesome is that the buffers can add to the gain, easing the burden on the difference amplifier in the second stage. The instrumentation amplifier perfectly combines all the previous material: inverting and non-inverting amplifiers in cascade.

We will not cover integrators, differentiators, oscillators or AD converters in this tutorial. Once we start adding capacitors and inductors, the math gets a bit more specialized and generalized in terms of impedance rather than resistance.

These will be a separate tutorial. If we look at a data sheet for the LM audio amplifier , we'll see a ton of parameters that help characterize the op amp. Most of these can be verified with simulation in LTSpice. Before we can get there let's define some of these characteristics. Common mode rejection ratio CMRR measures the amount of signal common to both inputs that is not amplified.

It is desirable for the common mode gain to be very low, which corresponds with a very high CMRR. The common mode rejection ratio is the ratio of the absolute value of differential gain to the absolute value of the common mode gain. The differential gain is typically half the intrinsic gain of the MOS transistor set by the manufacturer. Op amps with high output resistance will feature the best CMRR. The last thing you want in your design is to have that ripple amplified through your op amp.

The takeaway here is that to minimize the effects of ripple in power supplies, the Op Amp is required to have a large PSRR. So keep that in mind when looking at data sheets for any upcoming projects. Slew rate refers to the maximum rate of change possible at the output of an op amp. Most op amps are slew rate-limited, and that is calculated by taking the max of the derivative, with respect to time of the output voltage of the op amp.

The task of an audio amplifier is to take a small signal and amplify it without making any changes other than amplifying it. This is a difficult task because unwanted signals i. Any deviation from linearity is considered a distortion. Harmonic distortion is a common form of distortion in audio applications where the peaks of the output signal get "clipped. Simulate, verify, build — my motto. In this case, the mini portable guitar amp project case, I took it too far. Set the amplitude and frequency of the signal high enough so that it is intentionally slewing.

This means that your sine wave output needs to have: dv out 2 A f Slew Rate dt Save the oscilloscope trace of the slewing output voltage. Now that you know what a slewing output voltage looks like, reduce the amplitude of the sine wave signal to ensure that it will not produce a slewing output. Measure the magnitude response of the voltage gain of the circuit from 1 Hz to 10 MHz, making sure to plot at least 3 points per frequency decade.

If you can measure out to f3db, write it in your lab worksheet. Also, write the measured gain A0 in your worksheet. Compare the magnitude response of the voltage gain in db for the two non-inverting amplifier circuits and the circuit from Problem 3. In this exercise, you will look at some of their limitations.
