DEVELOPMENT OF PHOTO RECEIVER TRANSIMPEDANCE AMPLIFER FOR LASER INTERFEROMETER SPACE ANTENA “LISA”

The laser interferometer space antenna (LISA) is a future space-based interferometric gravitational-wave detector led by the European Space Agency (ESA). LISA is planned to be launched in 2034. Currently, the device for LISA is being developed around the world, the role of the Japanese team is to develop photo receiver. Since the LISA photo receiver receives several hundreds of pW of laser light, the required noise level is smaller than 2pA/√Hz@30MHz. In order to achieve the noise requirements, we installed transistor-based circuit, “regulated common-base”, in the first stage transimpedance amplifiers. In this paper, we report the design, noise simulation and experimental situation of the photoreceiver transimpedance amplifiers
