    For the original article see ibid., vol. 38, p. 456-461 (1991). In the aforementioned paper two configurations for realizing second-order voltage transfer functions using a single current conveyor (CCII) were given. The commenter points out that there is an error in the basic equation of the first configuration and gives a corrected version of the equation. View full abstract»

    An algorithm to capture all the unicursal branches of any one-port characteristic in piecewise-linear (PWL) resistive circuits is described. The heart of this algorithm is based on the so-called polyhedral augmented circuits: they are constructed by replacing each PWL element by a suitable polyhedral element and by connecting a norator to the one-port. The structure of the algorithm is based on a ... View full abstract»

    In time reversal duality, pairs of networks have corresponding waveforms that are time reversed versions of each other. The relation linking a pair of generalized, nonlinear, time varying dynamical systems is derived. It is then applied to time invariant linear networks. Four types of time reversal circuit duality are possible, and in two of these the direction of energy flow is reversed View full abstract»

  • Class DE high-efficiency tuned power amplifier

    Publication Year: 1996, Page(s):51 - 60

    A new type of high-frequency high-efficiency tuned power amplifier is proposed, analyzed and verified experimentally. It is called a Class DE tuned power amplifier because its circuit topology is very similar to that of the conventional Class D amplifier and the operation of each switch satisfies the Class E switching conditions when the switch turns on. Class E switching conditions are achieved b... View full abstract»

    A DC-DC buck converter controlled by naturally-sampled, constant-frequency pulsewidth modulation in continuous conduction mode gives rise to a great variety of behavior, depending on the values of the parameters of the circuit. We analyze the one-periodic and two-periodic orbits which cross the voltage ramp once per cycle, and we study their stability by computing the characteristic multipliers as... View full abstract»

  • Exponential state space filters: a generic current mode-design strategy

    Publication Year: 1996, Page(s):34 - 42

    A new method of analog filter design is proposed where nonlinear active components are a natural part of a filter realizing an overall linear transfer function. This approach to design is articulated in the generation of the class of so-called “Exponential State Space” (ESS) filters. An outgrowth of “log filters”, ESS filters are created via a mapping on the state space of ... View full abstract»

  • A transformation method for equivalent infinite-gain op amp to unity-gain CCII networks

    Publication Year: 1996, Page(s):61 - 63
    Cited by:  Papers (16)

    A method to obtain equivalent networks is proposed. This permits one to synthesize filters with unity-gain CCII± from well-known single infinite-gain op amp configurations. Current transmittance filters with high output impedance and voltage transmittance filters with high input impedance are obtained. These circuits have the same passive sensitivities as their op amp counterpart... View full abstract»

    Amplifiers with high open-loop gain (operational amplifiers) are frequently encountered in analog signal processing circuits, since the application of negative feedback enables numerous transfer functions to be implemented. The designer wanting to select an operational amplifier for a given application is met with a vast range of devices, with different architectures optimized for particular syste...

    In this paper, we present a comprehensive theoretical study of the stability of current feedback op-amps, when used with both resistive and capacitive feedback. The paper identifies some of the more subtle features of designing with current feedback op-amps, and the impact these features have on the amplifiers stability. There is a common misconception that the current feedback op-amp will oscilla... View full abstract»
