A Circuit Design for Photodiode Array Based on FPGA

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.
