An op amp has a gain bandwidth product of 5 MHz, at what frequency the gain becomes unity?
Question
An op amp has a gain bandwidth product of 5 MHz, at what frequency the gain becomes unity?
Solution
The gain-bandwidth product for an operational amplifier (op amp) is a constant value that is a measure of the op amp's capacity to amplify a signal. It is given by the product of the amplifier's gain and the frequency at which the gain is measured.
In this case, the gain-bandwidth product is given as 5 MHz.
The question asks at what frequency the gain becomes unity. Unity gain means the output signal is the same as the input signal, i.e., the gain is 1.
Since the gain-bandwidth product is a constant, when the gain is 1, the bandwidth (frequency) is equal to the gain-bandwidth product.
Therefore, at unity gain, the frequency is 5 MHz.
