1. 1. 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. 4. Low Power Decoding Circuits for Ultra Portable Devices

   Författare :Reza Meraji; Institutionen för elektro- och informationsteknik; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

   Sammanfattning : A wide spread of existing and emerging battery driven wireless devices do not necessarily demand high data rates. Rather, ultra low power, portability and low cost are the most desired characteristics. Examples of such applications are wireless sensor networks (WSN), body area networks (BAN), and a variety of medical implants and health-care aids. LÄS MER

7. 5. Ultra-low Power Design Approaches in Memories and Assist Techniques

   Författare :Babak Mohammadi; Integrerade elektroniksystem; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Memory; SRAM; assist technique; charge pump; ULP; ULV;

   Sammanfattning : The need for more functionality and higher performance has increased the number of transistors to billions in current processors. A high number of transistors on the same chip area increases the power density, which in turn heats up the devices and lowers the life time of batteries. LÄS MER
