Static and dynamic hysteretic features in a PWL circuit

Abstract

The general properties of the static and dynamic hysteretic behaviours of a PWL ladder circuit are described and discussed. These properties are obtained on the basis of some results reported in a previous paper (M.Parodi et al., Int. j. circ. theor. appl., 22, 513 (1994), concerning the static hysteretic behaviour of the same circuit. Despite the non-linearity of the circuit, the main features of its hysteretic behaviour are shown to depend on the parameters of the circuit components in a simple way. Moreover this behaviour is similar to those observed in a large number of experiments. For these reasons, the PWL ladder circuit is taken as the central element of a general circuit model for hysteresis. The structure of this general circuit is described at the end of the paper.
