Design and Test of An EMCCD CCD201 Sensor Driving Circuit

Abstract

In order to improve the imaging quality in extremely low illumination situation, a driving circuit of high resolution and sensitivity camera was developed to use back illumination. Frame transfer electron multiplying gains (EMCCD) with 1024×1024 pixels named CCD201 from UK E2V technologies. The circuit uses integrated CMOS driver EL7457 and EL7156 as the driving module. A programmable control voltage power source was adopted for the electron multiplying voltage to realize program-EM control. A bias voltage circuit with a high efficiency and precision was designed for the CCD201 complex voltage supply system.
