Voltage-controllable magnetic skyrmion dynamics for spiking neuron device applications

Chinese Physics B, 2022
Voltage-controlled magnetic skyrmions have attracted special attention because they satisfy the requirements for well-controlled high-efficiency and energy saving for future skyrmion-based neuron device applications. In this work, we propose a compact leaky-integrate-fire (LIF) spiking neuron device by using the voltage-driven skyrmion dynamics in a ...

Voltage-spike analysis for a free-running parallel inverter

IEEE Transactions on Magnetics, 1974
Unwanted and sometimes damaging high-amplitude voltage spikes occur during each half cycle in many transistor saturable-core inverters at the moment when the core saturates and the transistors switch. The analysis shows that spikes are an intrinsic characteristic of certain types of inverters even with negligible leakage inductance and purely resistive

Spiking voltages for faster switching of nematic liquid-crystal light modulators

Applied Optics, 2006
Electrical address circuits developed for driving fast-switching ferroelectric liquid-crystal spatial light modulators (SLM) can be programmed to increase the speed of much slower responding nematic liquid-crystal SLMs. Using an addressing circuit that can switch as fast as 0.164 ms, voltages are programmed for values of phase that exceed the desired ...

Spike voltage topography and equivalent dipole localization in complex partial epilepsy

Brain Topography, 1990
The EEG of 45 patients with complex partial epilepsy was recorded from standard and supplementary inferior temporal electrode sites for 2 or more days via cable telemetry onto video (VHS) tape (22-25 channels, common reference). Epochs with "temporal spikes" were read into a topographic EEG device where individual spikes were visually identified and ...

Mechanism of Rectified Output Voltage Spike in Isolated Converter Under Wide Input Voltage

2018
There exists high rectified output voltage spike in isolated transformer’s secondary, especially for the high frequency link auxiliary inverters under wide input voltage. It will lead to increased voltage stress and loss of switching devices, impeding the improvement of system’s reliable operation and conversion efficiency.

A dual time—voltage window discriminator for multiunit nerve spike decomposition

Journal of Neuroscience Methods, 1983
Abstract Construction and operation of a dual time-voltage window discriminator is described. The device is not only sensitive to spike height but also to spike width. The discriminator is especially suited to decompose multiunit nerve spike sequences.

Discharge performance of conductor spikes in GIS under AC voltage

2017 IEEE Electrical Insulation Conference (EIC), 2017
Gas insulated switchgear (GIS) is widely applied in power systems due to its excellent insulation performance. The reliability of GIS will be influenced by various insulation defects generated during the manufacture, installation, adjustment, operation and maintenance of the apparatus. Some defects, including conductor spikes, free metal particles, etc.

Low-Voltage Oxide-Based Synaptic Transistors for Spiking Humidity Detection

IEEE Electron Device Letters, 2019
In order to obtain higher humidity sensitivity, shorter response/recover time, and lower energy consumption, we investigate the dynamic humidity sensing characteristics of indium–zinc-oxide (IZO)-based synaptic transistors with graphene oxide/chitosan composite electrolyte films as the gate dielectrics.
