A high step‐up coupled‐inductor‐based dc‐dc converter with a wide duty cycle range and improved gain‐to‐element ratio

IET Power Electronics
Most high‐gain step‐up dc‐dc structures operate with a limited duty cycle and suffer from a high component count, limiting their application. This paper addresses these problems by proposing a new step‐up dc‐dc converter that provides a high conversion ...

Solution‐Processed Thin‐Film Transistors With Tunable Temporal Dynamics for Neuromorphic Computing

Advanced Functional Materials, EarlyView.
Solution‐processed CNT and CNT/P3HT ion‐gated transistors exhibit materials‐defined synaptic timescales: fast CNT devices for high‐frequency spiking and slow hybrid devices for temporal integration. Embedding these dynamics into coupled reservoir‐computing and spiking neural network simulations reveals that a Hybrid‐Reservoir / CNT‐SNN architecture ...
