• ### A conceptual framework for ASIC design

Publication Year: 1988, Page(s):741 - 755
Cited by:  Papers (13)
| | PDF (1628 KB)

An attempt is made to gain a better understanding of the nature of ASIC (application-specific integrated circuit) design. This is done from a decision-making perspective, in terms of three knowledge frames: the design process, the design hyperspace, and the design repertoire. The design process frame emphasizes the hierarchical design approach and presents the methodology as a formalization of the... View full abstract»

A review is presented of the current technical status of large-diameter GaAs crystal growth, the effects of residual impurities, stoichiometric defects and crystalline imperfections on the electrical properties of undoped semi-insulating GaAs, and the effectiveness of Group III and V isovalent, lattice-hardening dopants in yielding dislocation-free, semi-insulating GaAs crystals. Factors related t... View full abstract»

• ### The application of gallium arsenide integrated circuit technology to the design and fabrication of future generation digital signal processors: promises and problems

Publication Year: 1988, Page(s):816 - 834

| | PDF (2370 KB)

The development of gallium arsenide digital integrated circuit technology has progressed rapidly during the past decade. It is argued that in order to derive the maximum benefit from this technology as it is inserted into next-generation signal and data processors, all aspects of the design, assembly, testing, and maintenance of the systems will have to be considered synergistically. Salient issue... View full abstract»

• ### On the generation of random numbers from heavy-tailed distributions

Publication Year: 1988, Page(s):838 - 840
Cited by:  Papers (2)
| | PDF (360 KB)

A method is described for the generation of random numbers using a modification of the rejection technique, which is useful when the inverse of the underlying probability distribution function is inexpressable or is expensive to compute. However, the rejection technique can also be expensive if the underlying distribution has heavy tails. The method proposed reduces this expense by computing the r... View full abstract»

• ### On the convergence speed of nonlinear least-squares IIR adaptive filter

Publication Year: 1988, Page(s):842 - 843
| | PDF (199 KB)

The authors investigate an infinite-impulse response (IIR) adaptive digital filter (ADF) based on the nonlinear least-squares (NLS) algorithm, and compare its convergence speed to that of a self-orthogonalizing IIR ADF which is known to have fastest convergence. By simulation, it is shown that the NLS IIR ADF converges faster than other known IIR ADFs, especially for a low-order case.<> View full abstract»

• ### Frequency dependence of GaAs FET equivalent circuit elements extracted from the measured two-port S parameters

Publication Year: 1988, Page(s):843 - 845
Cited by:  Papers (6)
| | PDF (298 KB)

An eight-element equivalent circuit for GaAs FETs is used to calculate their element values from the eight measured data values of the two-port S parameters exactly at each frequency. Three element values vary with frequency and two additional small inductances are needed to account for the frequency dependence. A ten-element equivalent circuit including these correction inductances closely predic... View full abstract»

• ### Analysis of an algorithm that resolves oscillatory data into smooth components

Publication Year: 1988, Page(s):849 - 851
Cited by:  Papers (1)
| | PDF (261 KB)

An algorithm for extracting smooth functions from oscillatory data by D.A. Ksienski (1985) was tested for accuracy. It was generally found that the algorithm does not accurately reproduce smooth input functions. Yet, when the smooth functions produced from this algorithm were used for interpolation, satisfactory results were obtained. It is concluded that this algorithm can therefore be utilized f...

Digital gallium arsenide (GaAs) integrated circuits offer prospects for high-performance electronics, particularly for increased speed and radiation hardness. Prototype GaAs devices fabricated in technologies ranging from ion-implanted metal semiconductor field-effect transistors (MESFETs) and junction field-effect transistors (JFETs) to epitaxial heterostructures, such as high-electron-mobility t...

• ### Simplification of MUSIC and ESPRIT by exploitation of cyclostationarity

Publication Year: 1988, Page(s):845 - 847
Cited by:  Papers (102)  |  Patents (1)
| | PDF (284 KB)

It is shown that for the problem of multiple-source location using antenna arrays, the algorithms MUSIC and ESPRIT can be simplified by use of the property called cyclostationarity, which is exhibited by modulated signals. The advantages of the modified algorithms are reduction in the required number of array elements and associated reduction in the SVD (singular-value-decomposition) computations....

The history of the development of the first LSI GaAs integrated circuits is outlined, with the focus on the technological context, people, motivations, key ideas, funding, etc. This development is claimed to have galvanized an enormous upsurge in interest in GaAs ICs both at an R&D level, and in commercializing the technology. The author's experience is followed from the GaAs planar localized ... View full abstract»

• ### Synthesis of high-resolution narrow-band Fourier spectra from low-resolution transforms

Publication Year: 1988, Page(s):835 - 836
| | PDF (136 KB)

The practical limit to fast Fourier transform (FFT) size imposed by available computer memory limits the achievable spectral resolution. However, it is pointed out, the coefficients of a large transform can be directly synthesized from the coefficients of successive smaller transforms over the same frequency range View full abstract»

• ### Computation of single-tone spurious effects in radio communication systems

Publication Year: 1988, Page(s):840 - 841
Cited by:  Papers (6)
| | PDF (140 KB)

Since the probability of single-tone spurious interferences is greater than any other RFI (radio-frequency interference) disturbance, a straightforward semiempirical computational method is presented for disturbing single-tone spurious magnitudes and frequencies. Measurements on an analyzed UHF ratio system gave similar results. This method proved useful in the design and development of radio comm... View full abstract»

• ### An on-line least-squares parameter estimator with finite convergence time

Publication Year: 1988, Page(s):847 - 848
| | PDF (144 KB)

An online parameter-estimation algorithm is presented which has the following features: (1) it reduces to the linear least-squares (LS) estimator after a set of regression vectors that span the full dimension of the parameter space has been processed, and (2) when the regression model is linear in the parameters, the parameter and prediction errors converge to zero in finite time. Both continuous-... View full abstract»

• ### Comments, with reply, on Identification of truncated narrow band autoregressive processes' by P. Burrascano et al

Publication Year: 1988, Page(s):836 - 838
| | PDF (280 KB)

The commenter claims that there are both experimental and theoretical deficiencies in the paper by P. Burrascano et al. (see ibid., vol.74, p.1164-5, 1986) which he attempts to clarify. Experimental data presented in this paper contradict those presented previously. The theoretical deficiencies stem from a misapplication of previously published work. In replying, the authors explain the purpose of... View full abstract»

• ### Comments, with reply, on Fast interpolation algorithm using fast Hartley transform' by J.I. Agbinya

Publication Year: 1988
Cited by:  Papers (1)
| | PDF (84 KB)

The commenters point out and correct several errors in the original letter (ibid., vol.75, no.4, p.523-4, Apr. 1987). In replying the author states that some suggested corrections to the gain of the low-pass filter and the kernel of the cas function, respectively, are in order. But the author points out that Hsa et al. have introduced a further error into the cas function themselves. The correct v... View full abstract»

• ### On the number of Costas arrays as a function of array size

Publication Year: 1988, Page(s):851 - 853
Cited by:  Papers (16)
| | PDF (196 KB)

A conjecture that the number of Costas arrays is a monotonic increasing function of array size is disproved by extension of the known values to n=17. A probabilistic estimation formula is developed which predicts the peak at n=16 and tracks the known values to (typically) 5-6% View full abstract»
