In this video, the frequency response and the gain bandwidth product of an op-amp have been discussed.
Gain bandwidth product is a very important parameter of the op-amp. And it is quite often used for selecting specific op-amp for the particular application.
Frequency Response of the op-amp:
In open loop configuration, the gain of the op-amp is not constant and varies with the frequency. The gain of the op-amp remains constant up to the certain frequency and beyond that, it reduces at the constant rate of -20 dB/dec.
In open loop configuration, the bandwidth of the op-amp used to be very low (Few Hertz), because most of the today's op-amps are internally compensated. (By using the internal compensation capacitor)
This internal compensation ensures the stability of the op-amp output at high frequency when op-amp is used in the feedback configuration.
And second, it ensures that op-amp has a single cut-off frequency at till its gain reaches the unity gain.
Gain Bandwidth Product of Op-amp:
Because of the internal compensation, it is easy to identify the frequency of the operation if we know the gain of the op-amp. Or it is easy to understand the behavior of the op-amp with frequency.
And the product of gain and frequency remains constant till the unity gain frequency for the op-amp, which is known as the gain bandwidth product of the op-amp.
Gain bandwidth product is very useful when op-amp is used in the closed loop configuration. Using this closed loop configuration, we can find the cut-off frequency of the op-amp using this gain-bandwidth product.
For any op-amp gain bandwidth product = Unity Gain Frequency.
The timestamps for the different topics covered in the video is given below:
0:33 Frequency Response of the Op-Amp
1:25 Role of Internal Compensation Capacitor in the Frequency Response of the Op-amp
2:58 Gain Bandwidth Product of Op-Amp
5:40 Gain Bandwidth Product of Non-Inverting and Inverting Op-Amp

ALL ABOUT ELECTRONICS

Op amp gain-BW product and slew rate limiting are defined, discussed and demonstrated on the bench. This discussion applies to the majority of general purpose op amps on the market - as most op amps are internally compensated with a single dominant pole. High speed op amps, unconditionally stable op amps, non-unity gain stable op amps, high power opamps, etc. may not follow these characteristics because they are often compensated differently in their design. An LM358N is used for the example circuit. Other popular op amps like the LM741, etc. will behave in a similar way. Sometimes the slew rate limit of a device will be the dominant factor in determining the bandwidth, and other times the gain-bandwidth product will determine the resulting frequency response. The video demonstrates why this happens. Notes from the video are here:

Relationship between gain and bandwidth in op-amp circuits. Definition of unity gain frequency and gain-bandwidth product.

Views: 1659
Mateo Aboy

gain–bandwidth product for an amplifier is the product of the amplifier's bandwidth and the gain at which the bandwidth is measured.
Operational amplifiers that are designed to have a simple one-pole frequency response, the gain–bandwidth product is nearly independent of the gain at which it is measured; in such devices the gain–bandwidth product will also be equal to the unity-gain bandwidth of the amplifier.
For an amplifier in which negative feedback reduces the gain to below the open-loop gain, the gain–bandwidth product of the closed-loop amplifier will be approximately equal to that of the open-loop amplifier.

Operational amplifiers are used in many circuits - one of the main applications is in amplifiers. Here the operational amplifier gain is of key importance.
Although there are both inverting and non-inverting amplifiers which have their own calculations, there is a generic equation for these circuits. The generic formula can be used to develop the equations for the inverting and non-inverting configurations.
The gain of these operational amplifier circuits is governed by the level of negative feedback. Applying negative feedback provides a defined level of gain, wider bandwidth, lower distortion as well as a number of other advantages. However it is often the operational amplifier gain that is of major importance.
When looking at the inverting amplifier circuit, the equation for the circuit can be calculated from the simple formula Av = R2/R1.
For the non-inverting amplifier the gain is slightly different and can be calculated from the formula Av = 1+ (R2/R1).
It is also possible to use the non-inverting amplifier as a buffer amplifier with a unity voltage gain by looping the output back to the inverting input, i.e. R1 = infinity and R2 = zero. In this way the voltage gain can be calculated to be 1.
So in summary both inverting and non-inverting amplifier gain is easy to calculate using the simple formulas.

In this video, the slew rate of an Op-Amp has been explained with solved examples.
What is Slew Rate:
It defines the maximum rate at which the output of the op-amp can change. (How fast the op-amp is able to respond)
Unit of Slew Rate: V/us
Different Op-Amp has different slew rate and the value of slew rate varies from 0.1 V/us to 1000 V/us.
So, depending on the application the op-amp with specific slew rate needs to be selected which prevents the distortion of the output signal.
Causes of Slew Rate in Op-Amp:
The internal compensation capacitor in the Op-Amp is the main cause of slew rate in every Op-Amp.
The value of Slew rate depends on the value of this internal compensation capacitor and the charging or driving current.
Power Bandwidth of the Op-Amp:
The maximum frequency (for large signals) up to which there will not be any distortion in the output is known as the Power bandwidth of an op-amp.
This power bandwidth of the op-amp (slew rate limited maximum frequency ) is defined for the large signal (in volts), while the unity gain-bandwidth product is defined for the small signals (in mV).
If the input frequency is more than this maximum frequency, then the output signal will start getting distorted. And this kind of distortion in output is known as the slew rate induced distortion.
The timestamps for the different topics covered in the video is given below:
0:19 What is Slew Rate of an Op-Amp?

Op-amps are very common for amplifier and comparator circuit designs. This video tests common dual op-amp slew rate (response) at various frequencies and at a fixed gain. A square wave into the op-amp should output a similar square wave at an amplification multiple.
Setup (See Onstate video #147 for more information):
Signal: 210mVp-p square wave with 100mV DC offset and 1.0k series resistor to op-amp.
Op-amps 1: 10k/1.0k gain setup with 1.0k load to ground.
Oscilloscope top trace CH1: 0.1V/div. Input signal. Op-amp +pin. Top marker arrow is 0V.
Oscilloscope bottom trace CH2: 1.0V/div. Op-amp output signal. Bottom marker arrow is 0V.
Op-amp gain=~11
Power input: ~10V. DMM=frequency
Testing: Adjust input frequency until op-amp output decreases or distorts signal.
Output: CH1=0.21Vp-p +0.1V offset, CH2=2.3Vp-p +1.1V offset.
Slew rate: Slowest-Fastest. Fairchild LM258, On Semi LM258, TI LM358, TI TLC272, On Semi MC33072. For comparator or amplifying applications, a fast response op-amp is recommended. A slow op-amp may not pickup the input signal or output the required signal level.
Recommendation: Different response rates for different manufacturers. Important to read datasheet for proper use of op-amp.

The video is NOT intended to take a deep dive into the design considerations for the amplifier (The Signal Path Blog site already did a fine video on that). I discuss the basic equations for calculating the the in-band gain, as well as the low- and high- corner frequencies of the frequency response. All of these parameters - DC bias levels, bias currents, in-band gain and frequency response are then measured and shown. Notes in the video can be found here:

This is the second of five videos in the TI Precision Labs – Op Amps
curriculum that addresses operational amplifier bandwidth. In this training,
we’ll discuss open and closed loop gain, gain bandwidth product, and
quiescent current vs. bandwidth. We will also simulate the bandwidth of a
circuit and show that it correlates to our calculated results.

In this video, the non-inverting op-amp configuration and how to use Op-Amp as a buffer or as a voltage follower (Unity Gain Amplifier) has been discussed.
In this video, the input impedance of both inverting and non-inverting opamp configuration has also been derived.
And inverting and non-inverting op-amp configurations are compared with respect to input impedance.
Non-inverting Op-Amp:
In non-inverting Op-Amp configuration, the input is applied at the non-inverting terminal of the op-amp and feedback is applied from the output the inverting end of the op-amp.
In this configuration, the input and output voltages are in phase with each other.
The input impedance of this configuration is ideally infinite and practically it is very high.
Op-Amp as a buffer (Op-Amp as Voltage follower):
Op-Amp can be used as a buffer in the non-inverting configuration. In this configuration, output voltage follows the input voltage. Or in another way, the gain of the Op-amp is one (Unity). That's why it is also known as unity gain amplifier.
The input impedance of this configuration is very high and that is why it can be used to isolate the different circuit stages.
The timestamps for the different topics in the video is given below:
0:52 Non-Inverting O-Amp Configuration
1:51 Derivation of Closed Loop Voltage gain for Non-Inverting Op-Amp Configuration
5:00 Advantage of Non-Inverting Op-Amp configuration over Inverting Op-Amp configuration
6:09 Input Impedance of Inverting Op-Amp
7:25 Input Impedance of Non-Inverting Op-Amp
9:28 Op-Amp as Buffer (or Op-Amp as Voltage Follower)
This video will be helpful to all students of science and engineering in understanding the concept of non-inverting op-amp and understanding how to use the op-amp as a buffer or as a voltage follower.
