A kind of circuit used in driving large area CCD of high frame frequency was designed

and it used frame transfer area CCD FT18 as sensor. This kind of high speed driving circuit can increase the angle of visual field with the constant condition of video in trail

and solve the requirement of the big visual field of searching goal. First

the structure and the specification of area CCD FT18 sensor are introduced in this paper

then the circuits of working clock and power driver for the sensor are proposed. The noises of the video signal (KTC noise and 1/f noise) are filtered by using the correlated double sampling (CDS) technique

and the signal-to-noise ratio of the system is also enhanced. Radiation scale has been done after design. According to the scale experiment data

it is linear to be able to find out CCD to respond degree

have verified drive circuit work normal. Entire system adopts the Field Programmable Gate Array ( FPGA ) as key controller

and hardware is designed by the software which is based on the modularization design method from top to bottom. The development efficiency has been enhanced.
