The gain bandwidth product formula is a mathematical relationship in operational amplifiers that describes the trade-off between an amplifier’s gain and its bandwidth. It states that the product of the amplifier’s gain and its bandwidth is a constant, so increasing one parameter will result in a decrease in the other. The formula is used to calculate the frequency at which the amplifier’s gain drops to unity, known as the gain bandwidth product frequency (fGBW). It also determines the feedback network components (resistors and capacitors) to ensure stable operation.
