    It has been known that a given single op-amp RC sinusoidal oscillator has four distinctly different, equivalent, stable forms, This paper shows that with the op-amp replaced by a four terminal floating nullor, the number of such equivalent realizations of any given single op-amp oscillator are much more than four. Through some examples it is demonstrated that some of such additional realizations o... View full abstract»

    The interaction of low- and high-frequency oscillations in an RLC circuit with a nonlinear capacitance is studied from the point of the modern theory of dynamical systems. It is found that for a certain range of parameters such an interaction may cause chaotic instability, even under the weakly nonlinear excitation conditions. The scenarios and conditions that give rise to chaotic oscillations are... View full abstract»

    Using the available theory on linear threshold logic, the Discrete-Time Cellular Neural Network (DTCNN) is studied from a geometrical point of view, Different modes of operation are specified. A bound on the number of possible mappings is given for the case of binary inputs. The mapping process in a cell of the network is interpreted in the input space and the parameter space. Worst-case and avera... View full abstract»

  • Rate optimal scheduling of recursive DSP algorithms by unfolding

    We propose a novel criterion called modified generalized perfect rate graph (MGPRG) to facilitate efficient synthesis of recurrent digital signal processing (RDSP) algorithms on application specific multiprocessor systems. We prove that a rate optimal schedule, which is a multiprocessor realization with maximum throughput rate, exists if and only if the dependence graph of the corresponding RDSP a...

    The problem of iteratively solving linear equations of the form Ax = b, for a solution x, given b and an operator A, arises in several contexts in the circuits and systems area. The author presents a theorem for the iterative solution of such linear equations View full abstract»

  • An energy function method for determining voltage collapse during a power system transient

    Publication Year: 1994 , Page(s): 635 - 651

    The occurrence of a voltage collapse is often described as a small-signal stability problem resulting from a bifurcation of the equilibrium load flow equations as the bus loads and generator power injections incur small changes. However, during a transient period, a voltage collapse may occur as a bifurcation of the transient load flow equations as the generator rotor angles vary. The purpose of t... View full abstract»

    This paper describes an approach to the stability analysis of two-dimensional (2-D) digital filters that are modeled in the Fornashni-Marchesini state space using a class of generalized 2-D Lyapunov equations, the generalization was made based on the constant 2-D Lyapunov equation proposed recently by Hinamoto (see ibid., vol. 40, no. 2, p. 102-10, 1993). It is shown that the use of the generalize... View full abstract»

  • Hybrid MOS-bipolar transistor switching with profiled drive signal

    A method for switching MOS-bipolar transistor hybrids has been developed, which improves the transition performance and minimises the base drive power requirements in a split Darlington configuration with low on-state voltage. The type of wave shaping of the input control signal, enables unusually small and high speed MOSFETs to drive exceptionally high base current pulses for fast turn-on of a bi... View full abstract»

    The method of extended linearization is proposed for the systematic solution of sliding mode controller design in DC-to-DC power converters of the boost and the buck-boost type. A nonlinear sliding surface with suitable stabilizing properties is synthesized on the basis of the extension of a linear sliding design carried out for the parametrized average linear incremental model of the converter.
