基于FPGA的光电二极管阵列驱动设计

空间生命科学实验中所使用的仪器有其体积小、功耗低、稳定性好等特点,有别于地面使用的一些仪器设备。针对空间应用的分光光度检测技术,设计了一种基于Field Programmable Gate Array(FPGA)的光电二极管阵列驱动方法。设计中,根据空间使用的特点遴选器件与技术方案,在单片FPGA上实现对自扫描光电二极管阵列的驱动及数据采集。该设计具有集成度高、功耗低、适应性好等特点,与空间应用要求相符。

A Circuit Design for Photodiode Array

Different from the instrument used on ground, the instruments used for Space Life Sciences Experiment are small, low power consumption and well reliability. A circuit design for photodiode array (PDA) based on Field Programmable Gate Array (FPGA) is used for Space Spectro Photometry. In the design, devices and technic is applicable for space, and the PDA driver and data readout work has be done in one FPGA. With high integration, low power consumption and good adaptability, the design matches the space application.
