"Reversed" alamethicin conductance in lipid bilayers

Biophysical Journal, 1991
Alamethicin at a concentration of 2 micrograms/ml on one side of a lipid bilayer, formed at the tip of a patch clamp pipette from diphytanoyl phosphatidylcholine and cholesterol (2:1 mol ratio) in aqueous 0.5 M KCl, 5 mM Hepes, pH 7.0, exhibits an asymmetric current-voltage curve, only yielding alamethicin currents when the side to which the peptide ...

A Three-Level GaN Driver for High False Turn-ON Tolerance With Minimal Reverse Conduction Loss

IEEE Open Journal of Power Electronics, 2023
This paper presents a three-level gate driver for GaN HEMTs (Gallium Nitride High Electron Mobility Transistors) for high false turn-on tolerance and low reverse conduction loss during both dead time at turn-on and turn-off.

Characterization and optimization of active negative voltage driving circuit for CoolGaN HEMTs in a phase-leg configuration

Energy Reports, 2022
The high switching speed of GaN HEMT will cause serious crosstalk in the phase-leg configuration. The negative turn-off driving voltage is usually recommended to avoid the parasitic shoot-through.
