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 This video will be helpful to all students in understanding the frequency response and the gain-bandwidth product of the op-amp.

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: http://www.qsl.net/w/w2aew//youtube/opamp_GBWP_SlewRate.pdf

Through derivation and example, the impact of GBP on an inverting and non-inverting op-amp circuit is demonstrated. The relationship between GBP, DC open loop gain, and open-loop pole frequency is shown. Additionally, the relationship of GBP, closed loop DC gain, and closed loop bandwidth is explained and demonstrated.

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.

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.
