  1. 6. Polyunsaturated Fatty Acids Modifying Ion Channel Voltage Gating

    Författare :Sara Börjesson; Fredrik Elinder; Klaus Benndorf; Linköpings universitet; []
    Nyckelord :MEDICINE; MEDICIN;

    Sammanfattning : Voltage-gated ion channels play fundamental roles in neuronal excitability and therefore dysfunctional channels can cause disease. Epilepsy is such a disease, affecting about 1% of the population and being characterized by synchronous electric activity of large groups of neurons leading to various types of seizures. LÄS MER

  3. 7. Conformational Changes during Potassium-Channel Gating

    Författare :Jakob Renhorn; Fredrik Elinder; David Engblom; Stephan Pless; Linköpings universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; ion-channel; electrophysiology; neuron; Jonkanal; neurologi; elektrofysiologi; neuron; aktionspotential;

    Sammanfattning : Voltage-gated ion channels have a paramount importance in many physiological processes such as cell-to-cell communication, action potential-propagation, and cell motility. Voltage-gated ion channels are characterized by their ability to sense membrane voltage and to greatly change channel activity in response to small changes in the voltage. LÄS MER

  4. 8. Ultra-low Voltage Embedded Memories – Design Aspects and a Biomedical Use-case

    Författare :Oskar Andersson; Institutionen för elektro- och informationsteknik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; SRAM; CMOS; ultra-low voltage; ultra-low power; subthreshold; standard-cell based memories; atrial fibrillation; SRAM; CMOS; ultra-low voltage; ultra-low power; subthreshold; standard-cell based memories; atrial fibrillation;

    Sammanfattning : As the Internet of Things (IoT) era emerges the need for ultra-low power (ULP) devices is becoming more eminent. A research-proven approach to achieve ULP consumption is to aggressively lower the supply voltage (VDD) below or in the vicinity of the transistor threshold voltage (Vth) and operate the transistors in the subthreshold (sub-Vth) region.

  5. 9. Voltage sensor movements in shaker and HCN channels

    Författare :Roope Männikkö; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : Voltage-gated ion channels are crucial for electrical signaling in living organisms. They are composed of four similar subunits with six transmembrane α-helices, S1-S6. Each subunit contains a voltage-sensing domain, S1-S4, and an ion-conducting pore domain, S5-S6. LÄS MER

  7. 10. Static Power Reduction and Estimation in CMOS Circuits Considering Emerging Leakage Mechanisms

    Författare :Mindaugas Drazdziulis; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; subthreshold; CMOS; wake-up time; power gating; gate leakage; VLSI;

    Sammanfattning : Due to semiconductor technology advancements, the static power dissipation caused by leakage currents in CMOS circuits is growing at a much faster rate than dynamic power; the dominant power component. As a result, controlling and limiting static power becomes as crucial as controlling dynamic power. LÄS MER
