If anyone know pls tell me in Gain bandwidth product, gain in what manner (dB or voltage gain (Vo/Vi)) ?
The gain bandwidth product (GBW) is a measure of the frequency range over which an amplifier can amplify a signal with minimal distortion. It is calculated by multiplying the open-loop voltage gain by the -3dB bandwidth of the amplifier.
The gain bandwidth product is directly proportional to the open-loop voltage gain of an amplifier. This means that an amplifier with a higher voltage gain will typically have a higher GBW.
The decibel (dB) gain in the gain bandwidth product represents the ratio of the output voltage to the input voltage of an amplifier. It is a logarithmic unit that allows for easier representation of large ranges of gain values.
The gain bandwidth product is an important factor in determining the performance of an amplifier. A higher GBW allows for a larger frequency range over which the amplifier can amplify a signal without distortion. This is especially important in high-frequency applications.
The gain bandwidth product of an amplifier can be affected by various factors, including the type of amplifier circuit, the quality of the components used, and the operating temperature. Additionally, the presence of external load or feedback can also impact the GBW of an amplifier.
