    An accelerated computer-oriented procedure is introduced for determining the steady-state response of linear networks with internally and/or externally controlled switches. The technique is based on Newton's method for solving systems of equations, for which the Jacobian matrix is required. A method of computing this matrix, concurrently with the time-domain response, is presented. All possible sw... View full abstract»

    A new effective method is developed for finding bounds on the location of all the DC solutions of the circuits containing Ebers-Moll-modeled transistors and diodes. The circuit is represented by algebraic equations consisting of linear and nonlinear (exponential-type) parts. The method leads to the process of successive contraction of a region including all the solutions. The crucial point of the ... View full abstract»

    An efficient algorithm for evaluating the matrix polynomial I+A+A 2+…+AN-1 is developed. The proposed scheme is simple and eliminates the difficulties encountered in applying a procedure recently reported by D. Westreich (see IEEE Trans. Circuits Syst., vol.36, no.1, p.162-164, Jan. 1989) View full abstract»

    The effect of periodic clock jitter in switched-capacitor filters is analyzed, extending a previously introduced state-space approach. This procedure facilitates the evaluation of the effects of the internally generated noise sources upon the output spectral density. This makes it possible to evaluate the sensitivity of a specific structure to its switched-capacitor and operational amplifier noise... View full abstract»

    The cellular neural network framework developed by L.O. Chua and L. Yang (IEEE Trans. Circuits Syst., vol.32, Oct. 1988) is used to analyze the image filtering operation performed by the VLSI linear resistive grid. In particular, it is shown in detail how the resistive grid can be cast as a CNN, and the use of frequency-domain techniques to characterize the input-output behavior of resistive grids...

  • On the feasibility of load-independent output current in class E amplifiers

    Publication Year: 1992, Page(s):564 - 567

    The conventional class E topology can be configured to achieve simultaneous load-independent output voltage and load-independent efficiency. Because its dual may also provide load-independent voltage, the conventional topology was examined for the possibility of simultaneous load-independent output current and load-independent efficiency. It is shown that the only solutions to the sets of equation... View full abstract»

    A body of results is given concerning the character of the response of systems represented by approximately-finite-memory input-output maps G. Conditions are given under which, for example, the system's output approaches a limit as t→∞ whenever the input does. Of particular interest are theorems that concern the existence and properties of a certain unique extension of... View full abstract»

  • 2-D BIBO stability using 1-D wave model

    Publication Year: 1992, Page(s):570 - 576

    The bounded-input, bounded-output (BIBO) stability of 2-D shift-invariant systems is studied using the concept of the wave advance model, which converts the 2-D equation into a 1-D time-varying format. It is shown that the wavefront 1-D discrete Fourier transforms evolve according to a conventional time-invariant equation. The propagation model is used to develop 2-D BIBO stability criteria. The m... View full abstract»

  • Poles for networks of Markov queues

    Publication Year: 1992, Page(s):577 - 582
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (380 KB)

    A method for calculating the throughput of queuing network models is introduced. This method uses the concepts of poles in the complex plane to evaluate system performance and characterizes the system bottleneck as a certain extreme pole. This method allows the analyst to treat linear systems, controls, and some queuing networks with the common methodology of complex variable analysis View full abstract»

    An arbitrary passive load to be matched by a lossless equalizer to a resistive source so that system response approximates any desired gain shape over a prescribed band, e.g., rectangular, is considered. A least-squares optimization procedure is described that determines the equalizer design. The method stems from the real frequency technique and uses trigonometric basis functions (Wiener-Lee tran...
