The\nmethodology is general in that it only relies on a parallel interconnection of\nelementary voltage-controlled current sources. In contrast to controlling a\nnonlinear circuit through the parameter tuning of a state-space model, our\napproach is purely input-output. The circuit elements are controlled and\ninterconnected to shape the current-voltage characteristics (I-V curves) of the\ncircuit in prescribed timescales. In turn, shaping those I-V curves determines\nthe excitability properties of the circuit. We show that this methodology\nenables both robust and accurate control of the circuit behavior and resembles\nthe biophysical mechanisms of neuromodulation. As a proof of concept, we\nsimulate a SPICE model composed of MOSFET transconductance amplifiers operating\nin the weak inversion regime.","url_abs":"http://arxiv.org/abs/1805.05696v2","url_pdf":"http://arxiv.org/pdf/1805.05696v2.pdf","source":{"archive":"pwc-archive (Hugging Face), CC BY-SA 4.0","snapshot":"2025-07-28","licence_url":"https://creativecommons.org/licenses/by-sa/4.0/legalcode","row_kind":"abstracts"},"code_links":[{"paper_slug":"neuromodulation-of-neuromorphic-circuits","repo_url":"https://github.com/lukaribar/Circuit-Neuromodulation","is_official":0,"mentioned_in_paper":0,"mentioned_in_github":1,"framework":"none","reach":null}],"tasks":[],"methods":[],"datasets_introduced":[],"methods_introduced":[],"results":[],"syntology":{"syntology_url":null,"atlas_url":null,"mcp":null,"developers":"https://syntology.ai/developers"},"arxiv_metadata":null,"syntology_extracted_results":null}
