Abstract
The Interference Imaging Spectrometer (IIS) is the one of payloads of the Chang'e-1 (CE-1) lunar satellite, which is used to acquire the spectral information and the global distribution information about lunar minerals. In this paper, some information about the electronic subsystem design of the Interference Imaging Spectrometer (IIS) is given. First, the technical specifications and requirements, architecture, function and operating modes of the electronic subsystem are described briefly. Secondly, the focus plane assembly (FPA) including CCD, CCD driving circuits, CCD buffering circuits, CCD biasing circuits and low-noise preamp circuits is introduced. Thirdly, the video processing and control assembly including the correlated double sampling(CDS) circuit, the programmable gain amplifier circuit, the active filter circuit, the A/D conversion circuit, digital video signal buffers, the timing module, the output interface circuit is treated. Fourthly, the timing description and logical architecture are given. Finally, some results are supplied. After careful design, thorough analyses and simulation, sufficient debug and test, the design has satisfied the technical requirements and achieved the goal of the one-year on-orbit operation.
