Polarity‐Controlled Volatile HfO2 Memristors with Bimodal Conductance for Neuromorphic Synapses and Reservoir Computing

open access: yesAdvanced Science, Volume 13, Issue 3, 14 January 2026.
This study demonstrates a TiN/HfO2/ITO memristor exhibiting field‐induced bimodal volatile switching behavior originating from ion bombardment during sputtering. The dipole‐driven, polarity‐dependent states produce multilevel output responses that expand the reservoir's output dimensionality and enhance encoding diversity.

Analysis and Design of a DC‐to‐24 GHz Compact High‐Speed Inductor‐less SPDT Switch

open access: yesElectronics Letters, Volume 62, Issue 1, January/December 2026.
ABSTRACT A compact DC‐to‐24 GHz single‐pole, double‐throw switch with enhanced isolation, low insertion loss and high‐speed performance, by adopting a multiple series‐shunt structure, has been presented in this letter. The mechanism of multiple series‐shunt structures of the switch on isolation and insertion loss are analysed. To verify the feasibility,

Design of a Highly Efficient and Wideband Power Amplifier With a New Microstrip Low‐Pass Filter

open access: yesInternational Journal of RF and Microwave Computer-Aided Engineering, Volume 2026, Issue 1, 2026.
In this letter, a highly efficient and wideband power amplifier (PA) is proposed based on resistive–resistive series of continuous modes (Res‐Res SCMS) with a new microstrip low‐pass filter (LPF). By employing a conventional real‐to‐real impedance transformer, the output and input matching networks are realized by incorporating the transistor′s ...
