    Some circuits exhibit jump behavior. for example, this occurs when the velocity field specified by the \dot{i}_L and \dot{\upsilon }_c of the inductor and capacitor characteristics cannot be "lifted" on to the resistive constraint manifold. The (jump) behavior is viewed as the limit as View full abstract»

    This paper begins by presenting a powerful method which is easy to apply to many broad-band circuit design problems. Anyone with a broad-band design problem, which in the narrow-band case amounts to finding a point inside of a certain circle (say on the Smith chart), might find the method here very useful (Section I). Gain equalization problems fall into this category and the main subject of this ... View full abstract»

  • An l_m norm bound for state variables in second-order recursive digital filter

    Publication Year: 1981, Page(s):1170 - 1171

    We introduce a new approach for determining an l_m norm estimation of state variables in a second-order recursive digital filter. A bound with closed-form analytical expressions is obtained for any minimum realization configurations. For the uniform grid structure, it is shown that if the poles of the filter lie in a specific region, the proposed bound is bett... View full abstract»

    One of the fundamental problems with residue arithmetic is the difficulty associated with residue-to-decimal conversion. In this paper, several new efficient conversion algorithms are presented. They span a practical fixed-point dynamic range.running from 12 to 36 bits with execution speed measured in nanoseconds. The mathematical foundations of the developed methods are discussed in detail and re... View full abstract»

  • On the sensitivity of a class of wave digital filters

    The first-order sensitivity of Fettweis' wave digital filter is expressed in terms of those of its reference filter from which the wave digital filter is derived. With this explicit relation the numerically observed properties of the wave digital filter sensitivity are explained and the relation itself can be used as an efficient computing method when the sensitivities of the reference filter are ...

    A method of one-sided tolerancing is given to determine an optimum set of minimum dc current gains in transistorized circuitry. The method has been used to select transistors in economical low-frequency power amplifiers which must survive a severe environment with a specified probability of failure. View full abstract»

  • Synthesis of lossy-lumped-distributed cascaded networks

    The synthesis of lossy lumped-distributed networks is important for many applications; for example, in the analysis of large systems such as the interconnections of the circuits on an LSI or VLSI silicon chip, such networks have been used as models, and a solution of the synthesis problem will thus aid in the design of these chips. In this paper singlevariable realizability conditions and synthesi... View full abstract»

    Characteristics of a second-order digital all-pass network with all possible combinations of two coefficients are discussed, and the constraints that the system should be stable and the group delay characteristic on extremum are described. Approximation formulas are given for the maximum group delay and for the angular frequency at which the group delay attains its maximum value. Digital all-pass ... View full abstract»

    A class of new structures is proposed, for the realization of the recursive digital filter with poles near the unit circle, by introducing the particular type of delay replacement scheme in the existing digital filter structure and then, inserting, delays at the. proper places to avoid the delay-free loops. By applying the proposed method to the second-order direct form structures, new structures ... View full abstract»

  • A high-quality double integrator building-block for active-ladder filters

    Active-ladder filters, at high frequencies, require doubleintegrator building-blocks meeting certain stringent requirements, which are not completely satisfied by most of the existing active-compensated double-integrator units. These restrictions are discussed here, and a highquality circuit is pointed out, having all the necessary properties. View full abstract»
