In any amplifier design, it is always necessary to give utmost attention to its frequency response analysis. While applying frequency response for some application it is also important to extend the bandwidth of an amplifier. Increasing the bandwidth means increasing the upper 3 dB frequency and decreasing the lower 3 dB limit. Although there are different means by which this extension can be achieved, the authors have chosen the application of negative feedback for the purpose. They have derived some new topologies from these existing topologies which fulfill their bandwidth requirements. In this paper, they resenting a new approach based on the individual standard topologies which extend the bandwidth of the standard amplifier by 30%.
