AbstractA general procedure is presented to realize a two‐port impedance matrix by a generalized transformerlessLCladder network including the classicalLCladder structure as a special case. the realization process consists of repeatedly applying a subnetwork removal cycle for which six different cases are to be considered. the feasibility of the various subnetwork removals is characterized by formulating necessary and sufficient conditions on the impedance matrix. the application of the procedure is illustrated by a numerical exampl

摘要:

AbstractA technique for implementing fully integrated continuous time non‐switched capacitor filter has been recently reported in the literature. the technique uses a balanced structure using op‐amps, capacitors and MOS transistors operated in the non‐saturated region as voltage‐controlled resistors. In order to eliminate the non‐linearity of the MOS transistors over an extended voltage range the current techniques use fully balanced circuits. This paper provides a simple technique for cancellation of non‐linearities, thereby reducing the number of elements, and proposes several simple circuits. the technique is then used in the design of high‐

摘要:

AbstractWith the rapidly increasing complexity of circuits and systems, the ability adequately to design a diagnosable circuit or system is a prime requisite for rapid fault location. In the present paper, a necessary and sufficient condition for pseudo‐circuit generation is presented for the use of the pseudo‐circuit in the self‐test algorithm. to determine the diagnosability of a designed circuit, a testability condition is presented with examples. the unique feature of these conditions is that they depend only on the topological structure of a given circuit, not on the component values; therefore, these conditions can be implemented in both linear and non‐linear circuits or systems. With the aid of a computer, the test points may be generated automatically by the proposed algorithm. Based on the proposed algorithm, the design of testability can be esta

摘要:

AbstractA new simple circuit model for the MOS (metal‐oxide‐semiconductor) structure is presented. the model consists of three elements, namely,a linear capacitor, a non‐linear capacitorand aC‐dynamic element.Each component bears a simple relationship to the physical operating mechanism inside the MOS structure. the model can be used for simulating arbitrary MOS structure circuits under all operating conditions. In particular, it is capable of reproducing the structure's frequency‐dependent small‐signal characteristics. the model is also shown to exhibit many important and interesting dynamic behaviours underforward, reverse and sinusoidaloperating modes.The model is based mainly upon the device's physical operating principles. But perhaps the most significant implication of this model is that it is thefirst everto use adynamic elementto model the MOS structure from a physic

摘要:

AbstractIt is proved that ann‐port composed of ideal transformers, gyrators and ideal rectifiers has a unique solution for the port variables when it is excited by generators in series with strictly positive resistances. the multiplicity of solutions for the internal variables is discussed. Connections are established with the theory of linear inequalities and with the coloured branch theorem of graph theor
