  • A signal processing ASIC for an electronic nose

    Publication Year: 1994, Page(s):8/1 - 8/5
    IEEE is not the copyright holder of this material | Click to expandAbstract | PDF file iconPDF (304 KB)

    This paper describes the development of a multi-channel BiCMOS ASIC that is capable of measuring absolute and changes in resistance. As such it is used for interrogating sensors based on resistive arrays. The AS1C was initially developed as part of an integrated electronic nose based on conducting polymers. The integrated nose is a hybrid constructed on a multi-layer, thick-film ceramic substrate.... View full abstract»

  • Transmit and receive ASICs for an ultrasound imaging multi-element array transducer

    Publication Year: 1994, Page(s):6/1 - 6/5

    High resolution focused beams of ultrasonic energy are used for imaging purposes for example by the medical profession and in non-destructive testing. High resolution beam focusing is achieved by pulsing the elements of an ultrasonic array transducer in some predetermined manner. This may take the form of a phased array, which allows for an electronically steered beam (sector scanning), or a linea... View full abstract»

  • Two dimensional, high resolution, charged-particle sensing ASICs

    Publication Year: 1994, Page(s):7/1 - 7/6
    IEEE is not the copyright holder of this material | Click to expandAbstract | PDF file iconPDF (376 KB)

    Describes development of a high resolution imaging XPS spectrometer. The spectrometer was to consist of four main components. A high magnification input lens; double 180° concentric hemispherical analyzers; a transfer lens between the two analyzers; and a high spatial resolution two-dimensional charge injected device (CID) detector. The input lens was to operate in the imaging mode with a magn... View full abstract»

  • A reconfigurable ASIC front end

    Publication Year: 1994, Page(s):3/1 - 3/4
    Cited by:  Papers (1)
    IEEE is not the copyright holder of this material | Click to expandAbstract | PDF file iconPDF (188 KB)

    This paper describes the work carried out on developing a reconfigurable ASIC front end for an intelligent sensor system. It is part of a joint industrial and academic research programme in ASICs for smart sensors involving the University of Southampton, Lucas Advanced Engineering Centre and European Silicon Structures (ES2). A test chip has been produced which facilitates the investigation of var... View full abstract»

  • Microelectronics and microengineering: the technology combination of the future

    Publication Year: 1994, Page(s):1/1 - 1/2
    IEEE is not the copyright holder of this material | Click to expandAbstract | PDF file iconPDF (160 KB)

    The technology for complete integration of transducers, electronic measurement system and actuators on a single chip already exists, though microengineering is still in its infancy and development of a complete system on a chip will pass through a logical sequence. First generation systems will likely consist of separate sensor, actuator and electronic chips perhaps mounted in the same header. Sen... View full abstract»

    The defence group (DG) of THORN EMI electronics specializes in the design and manufacture of equipment for installation in guided weapon (GW) systems. These items of equipment often have to be installed in confined, peculiarly shaped spaces, such as the nose cone of a missile or shell, in order to be able to accommodate requirements for increased circuit complexity within the limited space envelop...

  • Software drivers for the reconfigurable ASIC analogue front end

    Publication Year: 1994, Page(s):4/1 - 4/4
    IEEE is not the copyright holder of this material | Click to expandAbstract | PDF file iconPDF (232 KB)

    The reconfiguration of the analogue front end of an intelligent sensor ASIC is implemented by means of analogue switches under digital control. A simplified diagram that concentrates solely on switching circuitry is shown. The configuration of this sub-system is determined by a vector of noughts and ones, which wholly determines its state. In an experimental version there are sixteen such switches... View full abstract»

  • Low-cost simulation of mixed-signal ASIC functionality

    Publication Year: 1994, Page(s):2/1 - 2/4
    IEEE is not the copyright holder of this material | Click to expandAbstract | PDF file iconPDF (260 KB)

    While searching for a method to retain engineering control of design, as for the first ASIC, while using the expertise of a silicon vendor led the author to develop the simulation method described in the paper. The approach is concerned mainly with analogue and quasi-static logic and is of such low-cost that it will allow even the smallest company to model an ASIC function and confirm its technolo...

  • ASICs for monitoring and controlling electric motors

    Publication Year: 1994, Page(s):10/1 - 10/4
    IEEE is not the copyright holder of this material | Click to expandAbstract | PDF file iconPDF (232 KB)

    Describes how ASIC design methods can be applied to the monitoring and control of electric motors and shows some of the system requirements and how they can be implemented using standard building blocks. By reference to a design case study, the use of an ASIC in the control of a DC electric motor shows that the functions of a microprocessor-based system can be replaced by a single ASIC View full abstract»
