Algebraic criteria for circuit realisations
نویسندگان
چکیده
This paper provides algebraic criteria for the number of inductors and capacitors which must be present in a realisation of a given electrical impedance function. The criteria are expressed in terms of the rank and signature of the associated Hankel, or Sylvester, or Bezoutian matrix, or equivalently in terms of an extended Cauchy index.

The complexity of Boolean functions from cryptographic viewpoint
Cryptographic Boolean functions must be complex to satisfy Shannon’s principle of confusion. But the cryptographic viewpoint on complexity is not the same as in circuit complexity. The two main criteria evaluating the cryptographic complexity of Boolean functions on F n 2 are the nonlinearity (and more generally the r-th order nonlinearity, for every positive r < n) and the algebraic degree. Tw...
متن کاملNumerical Analysis of DAEs from Coupled Circuit and Semiconductor Simulation
In this work we are interested in the numerical solution of a coupled model of differential algebraic equations (DAEs) and partial differential equations (PDEs). The DAEs describe the behavior of an electrical circuit that contains semiconductor devices and the partial differential equations constitute drift-diffusion equations modeling the semiconductor devices in the circuit. After space disc...
متن کاملNumerical stability criteria for di erential-algebraic systems
In this paper we transfer classical results concerning Lyapunov stability of stationary solutions x to the classes of DAEs being most interesting for circuit simulation, thereby keeping smoothness as low as possible. We formulate all criteria in terms of the original equation. Those simple matrix criteria for checking regularity, Lyapunov stability etc. are easily realized numerically.
متن کاملA current-mode CMOS loser-take-all with minimum function for neural computations
A novel architecture for loser-take-all functions is proposed. Inputs and outputs of the circuit are currents, which make the circuit appropriated for low-voltage neural hardware computation. In contrast to most existing realisations the circuit does not require subtraction from a fixed reference what decreases accuracy and input dynamic. Moreover, in addition to the loser, it also outputs the ...
متن کاملPitch accents and information status in a German radio news corpus
This paper presents a corpus analysis of prosodic realisations of information status categories in terms of pitch accent types. The annotations base on a recent annotation scheme for information status [1] that is based on semantic criteria applied to written text. For each information status category, typical pitch accent realisations are identified. Moreover, the relevance of the strict seman...
