    The periodic steady-state solution of nonlinear dynamic systems can be computed by the so-called quick steady-state methods, e.g., Newton iteration, optimization or extrapolation. These methods compute a vector z(t_{0}) of the periodic steady-state solution by requiring the solution to repeat itself periodically, z(t_{0}...

  • A heuristic thermistor model

    Negative temperature coefficient thermistors, traditionally characterized by a nonlinear relationship in the resistance-temperature space, are shown to be intrinsically linear when that characteristic is mapped into a space defined by an appropriate transform. Therefore, information formerly conveyed by scores of tabulated ordered sets is contained in a pair of first-order equations which define r... View full abstract»

  • A derivation of the switched-capacitor adjoint network based on a modified Tellegen's theorem

    A method of generating an adjoint network for switchedcapacitor (SC) circuits with periodic switching and piecewise-constant inputs is derived in a general manner using a modified form of Tellegen's theorem. The derivation is independent of the method used to formulate the network equations. It is shown that under certain conditions the adjoint network may be described by the transposed system equ...

  • Additive and multiplicative minimum-phase decompositions of 2-D rational power density spectra

    This paper considers the multiplicative and additive minimum-phase decompositions of a two-dimensional (2-D) rational power density spectrum (commonly known as the spectral factorization and partial fraction expansion problems). It is shown that both of these decompositions generally involve filters which are ratios of 2-D minimum-phase filters, with finite support in one variable, and infinite su... View full abstract»

  • Subharmonic Synchronization of Class-C Oscillator

    This paper discusses the phenomenon of synchronization of a class-C oscillator in the subharmonic mode and reports certain new phenomena. A mathematical method has been developed to account for the phenomena. The effect of the time constant of the automatic biasing circuit on the synchronization range, frequency characteristics, stability, and locking time of the oscillator has been studied. Exper...

  • A new approach to the design of tuned power oscillators

    Publication Year: 1982, Page(s):261 - 267
    Cited by:  Papers (3)
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (664 KB)

    A new method of the design of tuned power oscillators, based on the method of the equivalent two-terminal networks, is presented. By the use of the proposed method, a phase shift of the feedback network can be taken into account and the phase condition for oscillation can be fulfilled at the resonant frequency of the output matching network. Hence, it is possible to obtain the output power and the... View full abstract»

    In this paper, a technique is proposed to decompose a two-dimensional (2-D) cyclic convolution of two d_{1} \times d_{2} arrays, where d_{2} = 2^{m} with m > 1 , into many identical and independent 2-D cyclic convolutions of smaller size. Using this technique and the fact that fa... View full abstract»

  • Analysis of transmission-line signal distribution to multiple ports

    The frequency response of a characteristically terminated transmission line, with multiple lumped discontinuities (output port loads) along the line, is determined. The analysis applies steady-state transmission-line solutions and simple circuit analysis methods in an iterative manner to determine the frequency response of each output port. This method is applied to the case of equally spaced capa... View full abstract»

    Based on the concept of generalized Euler-Lagrange equations, this paper develops a Lagrange formulation of RLC networks of considerably broad scope. It is shown that the generalized Lagrange equations along with a set of compatibility constraint equations represents a set of governing differential equations of order equal to the order of complexity of the ne...

    In this paper, a new high-gain three-port operational amplifier (OA) circuit is used to replace the single OA in single amplifier biquads (SAB's). The resultant biquads will have the first-order effect of the OA's finite gain-bandwidth products (GB) completely eliminated from their dominant pole frequencies. Then, the widely used bandpass filter will be considered, where the remaining dominant sec... View full abstract»

  • A new method for the design of 2-D filters with guaranteed stability

    A new method-based on transformations from 1-variable transfer functions is presented for the design of stable 2-variable transfer functions. As compared with already existing methods, this method results in a good response obtained through fewer numbers of iterations. The designed filters are always stable without the need of any constraints during minimization. View full abstract»

    The unit noise gains for optimal and parallel normal realizations of digital filters can be expressed in terms of a set of noise gain parameters that are simply related to the pole locations and pole residues. These noise gain parameters are shown to be invariant under a class of frequency transformations, and for digital filter transfer functions derived by bilinear transformation of an analog tr...
