    A new logic element, My-box, is proposed to model the line faults (stuck-at-1 and stuck-at-0) and the transistor faults (stuck-on and stuck-open) of CMOS circuits, which consist of fully CMOS logic, pseudo NMOS logic, dynamic CMOS logic, clocked CMOS (C/sup 2/MOS) logic, CMOS domino logic and NORA CMOS logic. It can also be used to model the faults and the functions of a transmission gate logic. A... View full abstract»

  • Switchbox routing with rerouting capabilities in VLSI design

    Publication Year: 1990, Page(s):210 - 218

    The macrocell approach to the design of VLSI integrated circuits needs a tool for the solution of the switchbox problem, where terminals lie on all the edges of a generic rectilinear region. In the paper, such a problem is thoroughly analysed and a two-layer symbolic router is proposed, which is able to successfully route very dense examples of switchboxes. The program applies a suitable algorithm... View full abstract»

  • New orthogonal series approach to state-space analysis of 1-D and 2-D discrete systems

    Publication Year: 1990, Page(s):205 - 209

    An orthogonal series approach is presented for state-space analysis of 1-D and 2-D linear time-invariant discrete systems. This approach makes use of the backward shift operation matrix derived in the paper, and yields explicit expressions for the state and output orthogonal coefficient matrixes. These expressions involve only multiplication of small dimension matrixes thus simplifying the computa... View full abstract»

  • An electronic nose: a sensitive and discriminating substitute for a mammalian olfactory system

    The dram of a direct electronic analogue for a biological nose may still be some way from realisation, but considerable progress can be reported towards prototype computerised instruments capable of equivalent, or even better, performance in certain applications. The achievements are partly attributable to success in new circuit and systems approaches, as well as in developing sensing devices, wit... View full abstract»

  • Design of one-dimensional systolic-array systems for linear state equations

    Publication Year: 1990, Page(s):185 - 192
    IEEE is not the copyright holder of this material | Click to expandAbstract | PDF file iconPDF (557 KB)

    To solve linear state equations, a two-dimensional systolic-array system has been proposed. For the same purpose, various kinds of one-dimensional arrays have been designed and discussed by the authors. The linear systolic-array system with first-in-first-out (FIFO) queues can be designed by applying double projections from the three-dimensional dependence graph (DG). As the array thus designed ne... View full abstract»

  • Voltage-controlled three terminal GaAs negative differential resistance device using n/sup +/-i-p/sup +/-i-n/sup +/ structure

    Publication Year: 1990, Page(s):219 - 224
    IEEE is not the copyright holder of this material | Click to expandAbstract | PDF file iconPDF (437 KB)

    A novel three terminal GaAs n/sup +/-i-p/sup +/-i-n/sup +/ negative differential resistance device prepared by molecular beam epitaxy is demonstrated for the first time. The peak-to-valley current ratios can be modulated by the third external applied voltage which can be expressed as I/sub p//I/sub v/=5.08*10/sup -3/ exp (1.999 V/sub BE/) at room temperature, where V/sub BE/ is in volts. It implie... View full abstract»

  • Class E/sup 2/ resonant DC/DC power convertor

    Publication Year: 1990, Page(s):193 - 196
    Cited by:  Papers (1)
    IEEE is not the copyright holder of this material | Click to expandAbstract | PDF file iconPDF (349 KB)

    A new high-frequency high-efficiency resonant DC/DC convertor is introduced. It is composed of a Class E inverter and a Class E rectifier. The convertor operates with load resistances ranging from a full load to infinity. It can regulate the output voltage by varying the switching frequency over a narrow range, owing to a high value of the loaded quality factor Q/sub L/ (>or=5). The measured relat...
