Extensional Framework for Pinched Hysteresis Systems

Abstract

Recently, the pinched hysteresis loop phenomenon discovered in many nanoscale devices has been a hot research topic. This paper proposes a new mathematical framework for those hysteresis systems to accommodate those discontinuity or not “well-defined” situations in canonical model of memristive system. In particular, two special subtypes are pointed out to fit the hitherto memory device characterization data. By Atting the I-V hysteresis loop, the effects of the transfer function in output equation on hysteresis loop properties are analyzed.

Keywords:

• Canonic
• Circuit model
• Dynamic system
• Memristive
• Pinched hysteresis
