The driver system of CCD is one of the key parts of a digital camera
which is related to camera’s technical parameters. After the inner structure and driver timing of a interline area-CCD KAI-1010M being introduced briefly
a CCD driver circuit which is used in the digital space survey camera
is designed with cheap products in a new way
the high speed and low cost is achieved in the same time. To resolve the technical difficulties
the pulse width modulation technology
which is usually used in the power supply and motor control
is introduced into the CCD driver circuit and a ultra-high speed operational amplifier is adopted to reduce the high speed negative signal’s rise and fall time。The results show that the CCD driver system can output two groups of CCD signals simultaneously in data output speed of 15 frame/s . The driver system can meet the need of the camera system because of its good function and low cost. If improved
the CCD driver system can output two groups of CCD signals in data output speed of 27 frame/s.
