Question
An op amp has a gain bandwidth product of 5 MHz, at what frequency the gain becomes unity?5000 kHz(5000×2) kHz1000 kHz(1/5000) kHz
Solution 1
The gain becomes unity at the frequency equal to the gain-bandwidth product. Therefore, for an op amp with a gain-bandwidth product of 5 MHz, the gain becomes unity at 5 MHz.
Solution 2
The gain becomes unity at the frequency equal to the gain-bandwidth product. Therefore, for an op amp with a gain-bandwidth product of 5 MHz, the gain becomes unity at 5 MHz.
