Jump resonance in the driven Chua's circuit to design frequency selective devices

Abstract

The onset of jump resonance in the driven Chua's circuit is deeply described in this paper, further confirming the role of Chua's circuit in nonlinear circuits and systems theory. The study of the conditions under which this peculiar behavior occurs is based on the possibility of obtaining a Lur'e representation of the driven Chua's circuit and applying the describing function approach. Design considerations to select the Chua's circuit parameters in order to shape the jump resonance features are given, providing the nonlinear core for highly selective frequency drift sensors.
