资料介绍

提供了一种针对电子倍增cCD(EMCCD)驱动电路的设计方案。通过FPGA编程产生符合EMCCD时序要求的信号波形,采用EL7457高速M0sFET驱动芯片对FPGA输出信号进行电平转换以满足EMccD驱动电压要求,并由分立的推挽放大电路驱动高电压信号,输出电压20~50V可调,像素读出频率达5MHz。实验结果表明,该驱动电路能够使EMCCD正常工作输出有效信号。

A design method is provided for driving circuit of electronic multiplication CCD (EMCCD). Waveforms in accordance with the requirements of EMCCD timing sequence are generated by field pro- grammable gate array (FPGA). Level conversion is performed to FPGA output signal by EL7457 high speed metal-oxide-semiconductor field effect transistor (MOSFET) driving chip so as to meet the requirements of EMCCD driving voltage. And high voltage signals are driven by discrete push-pull amplifier circuits. Out- put voltage can be adjusted from 20 V to 50 V and pixel read frequency is 5 MHz. Experimental results show that EMCCD is at normal operation state in the driving circuit and effective signals are output.
