CCD Linear Image Seor MND 8-Bi High-Respoiviy CCD Linear Image Seor wih Inernal Clock Driver Overview The MND is a high respoiviy CCD linear image seor having floaing phoodiodes in he phoodeecor region, CCD analog shif regisers for read ou, and a buil-in clock driver. I provides large oupu a a high S/N raio for visible ligh inpus over a wide range of wavelengh. Feaures 8 floaing phoodiodes and n-channel buried ype CCD shif regisers for read ou are inegraed in a single chip. Since a clock driver circui is buil in, i is possible o drive his device using CM or TTL logic. Large signal oupu of ypically m a sauraion can be obained. Because a sample hold circui is buil in, he oupu waveform makes signal processing easy. Since a compeaion oupu pin () is provided in addiion o he signal oupu pin (), i is possible o obain a signal wih a high S/N raio by carrying ou differenial amplificaion of he and oupus. Operaion wih a single posiive power supply.

CCD Linear Image Seor MND Corucion of he Image Seor The MND can be made up of he hree secio ofa) phoo deecor region, b) CCD rafer region (shif regiser), and c) oupu region. a) Phoo deecor region The phooelecric conversion device coiss of an µm floaing phoodiode and a µm channel sopper for each pixel, and 8 of hese devices are linearly arranged side by side a a pich of µm. The phoo deecor's windows are µm µm recangle and ligh inciden on areas oher han hese windows is opically shu ou. The phoo deecor is provided wih opically shielded pixels (black reference pixels) which serve as he black reference. b) CCD Trafer region (shif regiser) The ligh oupu ha has been phooelecrically convered is raferred o he CCD rafer for each odd and even pixel Drive Circui Diagram (Digial Secion) C C.
