Manufacturers insert a dominant pole in the op amp frequency response.

This constant is usually known as the Gain Bandwidth Product(GBP, GB). The Gain Bandwidth Product describes the op amp gain behavior with frequency. The open-loop frequency response curve shown above we can observe that the product of the gain against frequency is steady at any point along the curve and in addition to that we can see the unity gains (0dB) frequency also determine the gain of the amplifier at any position along the curve. 7.19 GAIN BANDWIDTH PRODUCT The parameter f as discussed in the preceding section is the frequency at which the shortcircuit current gain of a CE. (Electronics Tutorial about Operational Amplifiers) It can limit the range for wavelength tuning Open-loop Frequency Response Curve Gain bandwidth product is commonly uses in the operational amplifier to let circuit designers to determine the highest gain that can be extorted from the apparatus for a given frequency (or bandwidth at any constant point)Ī little gain bandwidth is desirable for constant single-frequency operation The gainbandwidth product (designated as GBWP, GBW, GBP, or GB) for an amplifier is the product of the amplifiers bandwidth and the gain at which the. For an operational amplifier, the gain-bandwidth product for one configuration will always equal the gain-bandwidth product for any other configuration of the same amplifier. When the gain is 100, the bandwidth will be 10 kHz. When the gain is 10, the bandwidth will be 100 kHz. When the gain is 1, the bandwidth will 1 MHz.

Refer to the multiple of the open loop gain (continuous for a given amplifier). The Gain-Bandwidth of the circuit (usually amplifier) is the product of the bandwidth and the gain at which the bandwidth is measured. The simplest way to remember the formula is that GBWP is exactly as it describes, that it is the product of gain and bandwidth, when the gain is 1 and the bandwidth is 1 MHz (in this example). What is Gain bandwidth product (GBW OR GB?)
