Abstract
In this paper, an amplifier that is compatible with Acoustic Emission sensor(AE sensor) system is proposed. An amplifier is the most important part of the AE sensor system. To overcome the shortcomings that is hard to distinguish between normal and defect product, wide bandwidth characteristic is needed. In this simulation, the proposed op-amp covers 0 to 150 kilo hertz in the range of operation. At the same time, it has 60dB gain.
