Beyond Impedance Additivity: A Systematic Nonlinear Perspective on Memristor Associations
Luiz A. Meneghetti, Leonardo K. Castelano, Antônio Sérgio dos Santos +5
We investigate the validity of the superposition principle and impedance additivity in AC circuits containing a memristive device connected in series with a resistor, capacitor, or…
Phase-Topology Classification of Memristor Hysteresis Loops via Self-Crossings
Ovidiu-Zeno Lipan, Eric Neuhaus, Rafael Schio Wengenroth Silva +6
Memristive devices have revolutionized non-volatile memory and neuromorphic computing, yet the geometry of their hysteresis loops -- in particular, the occurrence and robustness of…
Gate-controlled analog memcapacitance in LaAlO3/SrTiO3 interface-based devices
Soumen Pradhan, Victor Lopez-Richard, Igor Ricardo Filgueira e Silva +8
Current memcapacitor implementations typically demand complex fabrication processes or depend on organic materials exhibiting poor environmental stability and reproducibility. Here…
2D Canonical Approach for Beating the Boltzmann Tyranny Using Memory
Rafael Schio Wengenroth Silva, Soumen Pradhan, Fabian Hartmann +4
The 60 mVdecade subthreshold limit at room temperature, coined as the Boltzmann tyranny, remains a fundamental obstacle to the continued down-scaling of conventional transistors…
Oxide Interface-Based Polymorphic Electronic Devices for Neuromorphic Computing
Soumen Pradhan, Kirill Miller, Fabian Hartmann +9
Aside from recent advances in artificial intelligence (AI) models, specialized AI hardware is crucial to address large volumes of unstructured and dynamic data. Hardware-based AI,…
Accuracy Bottlenecks in Impedance Spectroscopy due to Transient Effects
Victor Lopez-Richard, Soumen Pradhan, Leonardo K. Castelano +4
