1. Towards Low-Voltage, High-Current : A pioneering drive concept for battery electric vehicles
Sammanfattning : The first electric low-voltage vehicles were constructed in the mid-19th century, but by the early 20th century they were progressively replacedby successors with internal combustion engines. As the consequences ofusing fossil fuels are better understood, our society is now transitioning back. LÄS MER
2. Low Voltage CMOS Radio Receiver Front-End Design
Sammanfattning : The mass production of integrated circuits for digital electronics has made CMOS technology the most frequently used IC process today. Thanks to the large production volume, CMOS has increasingly become the most cost efficient technology of choice, and the fast development of small, high speed CMOS devices has made the technology feasible for many RF applications.

3. Propagation of Supraharmonics in Low-Voltage Networks
Sammanfattning : The need for measures towards a sustainable use of energy has incited the proliferation of devices and systems for the efficient use of electricity. Energy-efficient appliances, equipment for the electrification of transportation, electricity generators from renewable energy sources, and communication protocols, e.g. LÄS MER
4. On voltage fluctuations in low voltage grids – characterization, propagation and impact on LED lamps
Sammanfattning : The work presented focuses on voltage fluctuations produced by household devices and their impact on the light output of LED lamps. Voltage fluctuations can produce unsteadiness on the light intensity of the lamps, so-called light flicker. An observer may or may not experience light flicker, depending on e.g. LÄS MER
5. Ultra-low Voltage Embedded Memories – Design Aspects and a Biomedical Use-case
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.
