Design of EMBCCD high voltage multiplier clock driving circuit in low-light level imaging system

Abstract

For EMBCCD (Electron-Multiplying Back Illuminated CCD) which is low light level imaging device, EMBCCD high voltage multiplier clock driver circuit is the key to realizing EMBCCD chip gain function and low light imaging. Through the circuit software simulation, circuit board production and experimental testing, we observed high voltage multiplier clock driver waveform that meets the requirements. When this circuit was used in the integral low-light level imaging system, the luminance of the video on the monitor was strengthened. Then the amplitude of high-voltage drive waveform was adjusted, the video luminance changed along with the high voltage drive waveform amplitude.
