However, accurate device models are often too complex for efficient circuit-level simulations.<\/p>\n<p class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\">This talk presents a compact modeling approach for threshold switching devices that combines circuit-level efficiency with a physically motivated description of the switching process. The model is developed starting from an LTspice macro-model, then extended through a mathematical description and a compact formulation based on an internal state variable. This internal state variable captures the delay associated with threshold switching and enables the model to reproduce the off-state, snapback region, and on-state behavior. The model is validated by fitting experimental current\u2013voltage data from an OTS device manufactured by Western Digital Research.<\/p>\n<p class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\">The talk will also discuss how this type of compact model can support circuit simulations involving nonlinear devices for memory and neuromorphic hardware applications.<\/p>\n<hr class=\"border-border-200 border-t-0.5 my-3 mx-1.5\" \/>\n<h2 class=\"text-text-100 mt-3 -mb-1 text-[1.125rem] font-bold\">Speaker Bio<\/h2>\n<p class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\"><a href=\"https:\/\/de.linkedin.com\/in\/alchawa\">Mohamad Moner Al Chawa<\/a> is a researcher in nanoscale device modeling and compact physics-based modeling of nonlinear electronic devices.
