“…The detailed specification and the performance of the plasma wave chip are described by Fukuhara et al (2012). Although we improved the chip design for the use in the prototype of the sensor probe, basic design was the same with that by Fukuhara et al (2011). Figure 4 shows a block diagram of the ASIC of the plasma wave receiver.…”

“…We use the application-specific integrated circuit (ASIC) for the preamplifiers of magnetic field sensors and waveform receivers. While the design and performance of the ASIC waveform capture is described by Fukuhara et al (2011Fukuhara et al ( , 2012, the description of the ASIC preamplifier of the magnetic field sensor will appear in the independent paper (Ozaki et al 2015). The conventional design is used for the preamplifiers of the electric field sensors, because of the necessity of very high impedance at the input.…”

Background: Since conventional one-point observations of plasma phenomena in space cannot distinguish between time and spatial variations, the missions on the basis of multiple-point observations have become the trend. We propose a new system for multiple-point observation referred to as the monitor system for space electromagnetic environments (MSEE). Findings: The MSEE consists of small sensor probes that have a capability to measure electromagnetic waves and transfer received data to the central station through wireless communication. We developed the prototype model of the MSEE sensor probe. The sensor probe includes a plasma wave receiver, the microcontroller, the wireless communication module, and the battery in the 75-mm cubic housing. In addition, loop antennas, dipole antennas, and actuators that are used for expanding dipole antennas are attached on the housing. The whole mass of the sensor probe is 692 g, and the total power consumption is 462 mW. The sensor probe can work with both inner battery and external power supply. The maximum continuous operation time on battery power is more than 6 h. We verified the total performance for electric field measurements by inputting signal to preamplifier. In this test, we found that analog components had enough characteristics to measure electric fields, and the A/D conversion and the wireless transmission worked correctly. In the whole performance for electric fields, the sensor probe has equivalent noise level of −135 dBV=m= ffiffiffiffiffi Hz p .

The design of plasma wave receivers for use onboard scientific satellites is introduced. Since space plasmas are collisionless, kinetic energy is transferred via plasma waves. The role of plasma wave receivers is to reveal wave-particle interactions in space plasma. Conventional plasma wave receivers are classified into three types: multichannel analyzers, sweep frequency analyzers, and waveform capture. Each one has their own advantages and disadvantages and thus they complement each other. The present paper provides guidelines for designing plasma wave receivers by referring to examples from representative science missions. Furthermore, the prospects of using plasma wave receivers in future missions are discussed. The mass and size requirements for onboard instruments can be satisfied by developing small receivers. Extremely small plasma wave receivers can be achieved using analog application-specific integrated circuit(ASIC) technology. We also introduce our recent progress in developing a chip that implements the necessary analog components of plasma wave receivers.

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. The present paper introduces a miniaturized on-board instrument for the observation of plasma waves using analogue applicationspecific 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 consumption of the system chip and the plasma wave receiver is 165 and 525 mW, respectively.
