等离子体波是科学卫星探测空间电磁现象的重要观测目标。对于未来的科学任务，在不损失性能的情况下减少等离子体波接收器的资源需求是很重要的。介绍了一种利用模拟专用集成电路（ASIC）技术的小型机载等离子体波观测仪器。所开发的ASIC作为系统芯片，对等离子体波传感器检测到的信号进行滤波和放大。利用ASIC实现了模拟电路的小型化，从而实现了微型等离子体波接收器。开发的等离子体波接收器电路板的整体尺寸小于以前科学任务中使用的传统接收器的1/20。系统芯片和等离子体波接收器的功耗分别为165和525 mW。
Plasma waves are important observational targets for scientific satellite missions to investigate electromagnetic phenomena that occur in space. For future scientific missions, reduction in the resource requirements of plasma wave receivers without loss of performance is important. This paper introduces a miniaturized on-board instrument for the observation of plasma waves using analogue application-specific integrated circuit (ASIC) techniques. The developed ASIC functions as a system chip to filter and amplify signals detected by plasma wave sensors. Miniaturization of the analogue circuit using the ASIC leads to the realization of a tiny plasma wave receiver. The overall size of the developed plasma wave receiver circuit board is less than 1/20 that of a conventional receiver used in previous scientific missions. The power consumptions of the system chip and the plasma wave receiver are 165 and 525 mW, respectively.
