摘要:

AbstractWe propose here an efficient algorithm for finding the steady‐state response of stiff non‐linear circuits. It is based on a frequency‐domain relaxation method and can be applied efficiently to obtain the steady‐state waveforms of both periodic systems and multi‐frequency‐component systems. the solution at each iteration is obtained by solving an associated linear time‐invariant circuit at every frequency component via modified nodal analysis. Our algorithm is very simple and can be applied efficiently to solve a large class of practical non‐linear communication circuits which are notoriously stiff and hence rather time‐consuming to solve with

AbstractAn impasse point of the implicit differential‐algebraic system.Has been characterized in Part I of this paper as alimit pointof aninduced solution curveIn this paper we use the Liapunov‐Schmidt procedure to derive an analytical test for identifying impasse points. We also invoke the transversality theory from differential topology to show that almost all singular points (Xo, yo) of S, which occur when the Jacobian matrixis singular, are in fact impasse poi

AbstractThis paper gives a detailed bifurcation analysis of a cusp‐constrained circuit in terms of the quantity ‘rotation‐jump ratio’. This turns out to be a very natural quantity to analyse various interesting bifurcation phenomena observed in the

摘要:

AbstractA systematic method for the simulation ofLCladders and unit‐element filters by means of switched capacitor (SC) circuits is proposed. the method is based on the use of wave equivalents of various two‐port subnetworks which are now realized by the same type of SC symmetric subcircuits. These subcircuits serve as the structural unit‐blocks for realizing high‐order circuits. Parasitic‐free circuits of practical interest can be developed. Examples of high‐order circuits are given. This wave method is simple in its concept and also in the circuit design. Through the alternative solutions which are described, the flexiblity of the method is d

摘要:

AbstractAn FIR filter design method with simultaneous amplitude and phase approximation is presented. Two components are proposed in the design method: simultaneous amplitude and phase interpolation in the passband and amplitude interpolation in the stopband. These interpolations are implemented by the Remez exchange algorithm.The polynomials for the interpolations are generated by recurrence formulae and the recurrence coefficients are calculated by a recursive method. the properties of the filters designed with the simultaneous approximation are investigated and compared with those of exact linear and minimum phase filters.
