    The development of large area c.c.d. image sensors is described and illustrated with the example ofa frame-transfer array with 385 × 576 image elements intended for 625-line television applications. The problems that still exist in meeting more demanding applications such as broadcast television are discussed and the various possible solutions are described. View full abstract»

  • A monolithic c.c.d. programmable transversal filter for analogue signal processing

    Publication Year: 1980, Page(s):213 - 225
    IEEE is not the copyright holder of this material | Click to expandAbstract | PDF file iconPDF (3889 KB)

    This paper describes the operational features and performance of a fully-integrated programmable transversal filter (p.t.f.), using c.c.d./m.o.s.t. technology. The choice of filter architecture for a prototype realization is discussed with particular reference to a novel multiplier array implementation using a single, time-multiplexed m.o.s. transistor. The performance characteristics of a prototy... View full abstract»

  • The applications of charge-coupled devices to infra-red image sensing systems

    Publication Year: 1980, Page(s):226 - 236
    IEEE is not the copyright holder of this material | Click to expandAbstract | PDF file iconPDF (3197 KB)

    The paper reviews the various ways in which c.c.d.s can be employed in i.r. sensing systems. These include: (i) monolithic structures fabricated using narrow band semiconductors such as HgCdTe or InSb, extrinsic silicon structures doped with deep-level impurities, and silicon Schottky barrier devices; (ii) hybrid structures in which the c.c.d. is used as the read-out mechanism from an array of, fo...

  • Multiplexed c.c.d.s for bandwidth compression applications

    Publication Year: 1980, Page(s):237 - 242

    A 321 -cell c.c.d. bandwidth compressor capable of analogue sampling at 100 MHz is described. This system is designed to accept data with a bandwidth of 50 MHz and subsequently to clock the data out at rates up to 2 MHz for recording on magnetic tape via a cheap, low speed a-d converter. Since power requirements are at a premium, low overall power consumption and high speed performance were essent... View full abstract»

  • C.c.d. integration techniques for clutter reduction in radar systems

    Publication Year: 1980, Page(s):243 - 248
    IEEE is not the copyright holder of this material | Click to expandAbstract | PDF file iconPDF (1006 KB)

    Substantial signal-to-clutter improvements are theoretically achievable using c.c.d.s to integrate a large number of returns. In practice, however, the performance of simple c.c.d. implementations is severely limited by charge transfer inefficiency, particularly if large range and high resolution are required. The paper describes several ways in which the effects of transfer inefficiency can be ov... View full abstract»

  • Advances in c.c.d. scanners with on-chip signal processing for electronic imaging

    Publication Year: 1980, Page(s):249 - 257
    IEEE is not the copyright holder of this material | Click to expandAbstract | PDF file iconPDF (1165 KB)

    The paper deals briefly with a few widely-used image signal processing algorithms and discusses how these can be incorporated on the same silicon chip as that of the c.c.d. scanner. Recent work on c.c.d. scanners is reviewed and solid-state scanners which include on-chip signal processing functions are described. Future trends are towards `smart¿ scanners; these are scanners with on-chip real-tim... View full abstract»

  • Basic c.c.d. logic gates

    Publication Year: 1980, Page(s):258 - 268
    IEEE is not the copyright holder of this material | Click to expandAbstract | PDF file iconPDF (2537 KB)

    The basic logic elements of AND, OR and INVERTER gates as implemented in c.c.d. logic are described and experimentally evaluated. The AND and OR gates are incorporated in one simple structure using the mechanism of charge spillage over a d.c. control gate from a common input well. Design equations are presented for the floating-gate master-slave sensing structure which is the basis of the inverter... View full abstract»
