    A systematic approach to derive practical CMOS sinusoidal oscillators is presented. A general topology is given to implement sinusoidal oscillators by using operational transconductance amplifier capacitor (OTA-C) techniques. To illustrate the proposed approach five different structures are presented from this general topology and analysed, taking into account the CMOS OTAs dominant non-idealities... View full abstract»

    In this paper the authors present a probabilistic approach in which the material is described in terms of a sparse scattering rate matrix. This one needs to be calculated only once by a Monte Carlo technique. Fluctuations are absent from the results. All devices using the same material recur to this matrix in terms of scattering. Results are for GaAs at 300 K using a 3-valley model. They agree wel... View full abstract»

  • Nonlinear MOSFET model for the design of RF power amplifiers

    A nonlinear equivalent circuit model for RF power MOSFET's is given. The model extraction uses cold S-parameter measurements. Pulsed drain current measurements are taken with the junction at the RF operating temperature. A method of thermally characterising the MOSFET is described. An equation is developed to represent accurately the drain current characteristics. The methods given are easily appl... View full abstract»

  • Design of a residue arithmetic multiplier

    Publication Year: 1992, Page(s):581 - 585

    The design of a pipelined residue-arithmetic multiplier is presented. The design uses multiple radices coded in binary. The multiplier accepts two 8-bit unsigned binary numbers and returns a 16-bit binary product. The five radices 7, 8, 11, 13 and 15, are chosen in a manner to give redundancy to numbers represented in residue arithmetic. This redundancy gives the multiplier an error-detection capa...

  • IIR filter design via optimal Hankel-norm approximation

    Publication Year: 1992, Page(s):586 - 590

    A new technique for digital filter design is presented. Based on the singular value decomposition of the Hankel matrix, balanced realisation and all-pass functions, an IIR filter is obtained via an optimal Hankel-norm approximation. The error between the optimal filter with order r and the desired filter is found to be equal to the (r+1)th singular value of the Hankel matrices. The designed low-pa... View full abstract»

  • Efficiency of feedforward amplifiers

    Feedforward amplifiers have found wide application in satellite and, more recently, mobile radiocommunications. In both of these fields it is important to be able to optimise the efficiency of the overall amplifier system and, in particular, select the optimum coupling factor for the output coupler in order to achieve this. The coupling-factor problem is examined mathematically and some results ar... View full abstract»

  • Diagnosis of multiple faults in combinational digital circuits by modelling of transition propagation along critical paths

    Publication Year: 1992, Page(s):594 - 606

    Previously published approaches to fault diagnosis in digital circuits rely almost exclusively on cause-effect reasoning. Such methods fail in the case of multiple faults, faults not easily modelled and faults not included in the set for other reasons. In contrast, a few attempts have been made to develop fault diagnosis methods utilising effect-cause reasoning. In the paper a new method of this t... View full abstract»

    In the paper, a spreadsheet simulation of a range of digital integrated circuits is presented. This simulation is characterised by its low cost, flexibility, and simplicity. The suitability of this simulation for educational purposes and its use with a course on logic design are also discussed.<> View full abstract»

  • Design of efficient digital filters satisfying arbitrary loss and delay specifications

    Publication Year: 1992, Page(s):611 - 620
    Cited by:  Papers (11)
    IEEE is not the copyright holder of this material | Click to expandAbstract | PDF file iconPDF (835 KB)

    Designing recursive digital filters satisfying both arbitrary loss and delay constraints is a classical problem. There is no known general analytical solution that can yield coefficient values. Many techniques have been proposed that offer various advantages, and some of these are reviewed in the paper. If, in addition, the particular application requires a high sampling rate, as in, for example, ... View full abstract»
