Question
An op amp has a gain bandwidth product of 2 MHz; at what frequency the gain becomes unity?(2000×2) kHz(1/2000) kHz1000 kHz2000 kHz
Solution
The gain bandwidth product of an operational amplifier (op amp) is a constant value that represents the op amp's frequency response. It is the frequency at which the gain of the op amp becomes 1 (or 0 dB).
Given that the gain bandwidth product is 2 MHz, this means that the gain of the op amp will become unity (1) at 2 MHz. Therefore, the correct answer is 2000 kHz.
