  • Monolithic amplifier with AGC and differential output for 622 Mbit/s optical communications

    Publication Year: 1999, Page(s):55 - 59
    IEEE is not the copyright holder of this material | Click to expandAbstract |PDF file iconPDF (420 KB)

    The authors deal with the implementation of a monolithic optical amplifier for SDH/SONET applications operating at speeds up to 622 Mbit/s. The amplifier incorporates automatic gain control (AGC) and differential output, so it is capable of being connected directly to a quantiser and a clock recovery chip-set. The presented design is fabricated on a cheap 1.2 μm BiCMOS technology which is actua... View full abstract»

    IEEE is not the copyright holder of this material | Click to expandAbstract |PDF file iconPDF (604 KB)

    A new, front-end image processing chip is presented for real-time small object detection. It has been implemented using a 0.6 μ, 3.3 V CMOS technology and operates on 10-bit input data at 54 megasamples per second. It occupies an area of 12.9 mm×13.6 mm (including pads), dissipates 1.5 W, has 92 I/O pins and is to be housed in a 160-pin ceramic quarter flat-pack. It performs both one- and...

    The silicon cochlea offers an interesting approach to implementing a hardware system for use in spatial localisation of a sound source. For such an application, knowledge of the different ways in which the cochlea has been implemented in silicon, together with the techniques necessary for sound localisation is essential. This review looks at how the auditory pathway has been modelled in silicon an... View full abstract»

  • Comment on “Circuit transformation method from OTA-C circuits into CFA-based RC circuits”

    Publication Year: 1999, Page(s):99 - 100
    IEEE is not the copyright holder of this material | Click to expandAbstract |PDF file iconPDF (80 KB)

    For the original paper see ibid., vol. 144, no. 4, p. 209-212 (1997). In the aforementioned paper Hou and Wang proposed a new and systematic method for transforming OTA-C circuits into CFA-based RC circuits. However, the commenter considers that there are some experimental results which should be corrected and that the transformation method could improved to simplify the design procedures View full abstract»

  • High-voltage sustaining structure with embedded oppositely doped regions

    Publication Year: 1999, Page(s):90 - 94

    A voltage-sustaining structure with embedded oppositely doped islands is proposed. Due to the compensation of the field induced by these regions, the doping density of the voltage-sustaining layer can be made larger than that in a conventional voltage-sustaining layer with the same breakdown voltage, and therefore the on-voltage can be reduced. The theory of design for such structures is found to ... View full abstract»

  • VLSI data demodulator for a microwave landing system

    Publication Year: 1999, Page(s):61 - 69
    IEEE is not the copyright holder of this material | Click to expandAbstract |PDF file iconPDF (840 KB)

    A VLSI circuit for demodulating the microwave landing system data format is presented. The approach is based on a second-order all-digital phase locked loop. The primary goal of the work is to find a cost effective way of embedding the demodulator within an integrated navigation receiver built around a customised application specific processor (ASP). While the fully digital nature of the design in... View full abstract»

  • Functional-level analogue macromodelling with piecewise linear signals

    Publication Year: 1999, Page(s):77 - 82
    Cited by:  Papers (3)
    IEEE is not the copyright holder of this material | Click to expandAbstract |PDF file iconPDF (492 KB)

    An analogue network macromodelling technique oriented towards functional-level simulation of both analogue and mixed analogue-digital networks is presented. The signals are assumed to be piecewise linear (PWL) waveforms. A class of nonlinear inertial building blocks is introduced for modelling. The proposed macromodels are accurate in their timing behaviour and computationally efficient, since an ... View full abstract»

  • Systematic approach to modelling and parameter extraction of an ion-implanted GaAs MESFET

    Publication Year: 1999, Page(s):95 - 98
    IEEE is not the copyright holder of this material | Click to expandAbstract |PDF file iconPDF (304 KB)

    The authors have modelled current/voltage characteristics of GaAs MESFETs built on ion-implanted substrates. It is shown that, for a physically acceptable model, some of the parameters should be voltage-dependent. This would account for the dopant nonuniformity in the channel and two-dimensional effects. For a very simple model, a minimum of five voltage-independent parameters was required (this n... View full abstract»

  • DC model for BiMOS structure and its adaptation to a circuit simulation environment

    Publication Year: 1999, Page(s):83 - 89
    IEEE is not the copyright holder of this material | Click to expandAbstract |PDF file iconPDF (516 KB)

    The objective was to develop a model that can accurately describe the hybrid-mode operation of deep submicron LDD pMOSFETs in a circuit simulation environment. The device threshold voltage, various current components, transconductance, and output conductance are extracted experimentally, modelled analytically, and adapted to meet the circuit simulation requirements. The latter necessitates that th... View full abstract»
