Limiting internal supply voltage spikes in DC-DC converters [PDF]

2009 IEEE International Symposium on Industrial Electronics, 2009
Implementing monolithic DC-DC converters for low power portable applications with a standard low voltage CMOS technology leads to lower production costs and higher reliability. Moreover, it allows miniaturization by the integration of two units in the same die: the power management unit that regulates the supply voltage for the second unit, a dedicated

Dendritic coincidence detection in Purkinje neurons of awake mice

eLife, 2020
Dendritic coincidence detection is fundamental to neuronal processing yet remains largely unexplored in awake animals. Specifically, the underlying dendritic voltage–calcium relationship has not been directly addressed.

Voltage‐dependent membrane potential oscillations of rat striatal fast‐spiking interneurons [PDF]

The Journal of Physiology, 2003
We used whole‐cell recordings to investigate subthreshold membrane potential oscillations and their relationship with intermittent firing in striatal fast‐spiking interneurons. During current injections (100–500 pA, 1 s), these cells displayed a highly variable pattern of spike bursts (comprising 1–30 action potentials) interspersed with membrane ...

Synapse-to-Nucleus Communication through NFAT Is Mediated by L-type Ca2+ Channel Ca2+ Spike Propagation to the Soma

Cell Reports, 2019
Summary: Long-term information storage in the brain requires continual modification of the neuronal transcriptome. Synaptic inputs located hundreds of micrometers from the nucleus can regulate gene transcription, requiring high-fidelity, long-range ...

Reduced Voltage Stress and Spikes in Source Current of 7-Level Switched-Capacitor Based Multilevel Inverter

IEEE Access, 2023
Various 7-level switched-capacitor (SC) based converters are reported in the literature which furnishes a voltage gain of 1.5. However, in these topologies, the voltage rating of switches is high and the switch count is more.

Phasic firing and coincidence detection by subthreshold negative feedback: divisive or subtractive or, better, both [PDF]

, 2017
Phasic neurons typically fire only for a fast-rising input, say at the onset of a step current, but not for steady or slow inputs, a property associated with type III excitability.

Impact of Transformer Design on Flyback Converter Voltage Spikes

Elektronika ir Elektrotechnika, 2016
The transformer design impact on voltage spikes, which arise on the drain of flyback converter MOSFET switch transistor, has been investigated. The special experimental model of flyback transformer was developed. The impact of transformer core air gap, windings design and windings position in transformer bobbin on the voltage spikes was investigated ...
