1. 1. Extending Wireless Power Transfer Range for Self-Powered Micro Devices with mm-size Antenna

   Master-uppsats, Linköpings universitet/Elektroniska Kretsar och System

   Författare :Natachai Terawatsakul; [2023]
   Nyckelord :;

   Sammanfattning : The primary challenge in expanding the wireless power transfer range for miniaturized self-powered micro devices is the limited RF energy harvesting due to the small effective area and low gain of the mm-sized antennas used in these devices. This thesis introduces a method for extending the distance between an external energy source antenna (TX) and a micro-device antenna (RX) to more than 10 cm. LÄS MER

   Sammanfattning : The market for Wi-Fi receiver designs for latest Wi-Fi standards, that cover RF bands in the 2.4 GHz, 5 GHz and 6 GHz spectrum, require increasingly stringent power consumption limitations as more of the market is driven towards battery-powered devices. LÄS MER

4. 3. Design and Modeling of InxGa(1−x)As/InP based Nanosheet Field Effect Transistors for High Frequency Applications

   Master-uppsats, Lunds universitet/Institutionen för elektro- och informationsteknik

   Författare :Hanyu Liu; Xi Chen; [2023]
   Nyckelord :nanosheet NS ; gate-all-around GAA ; channel release; parasitic channel; MATLAB; COMSOL; technology node; Technology and Engineering;

   Sammanfattning : The advancement of CMOS technology has been fueled by the need to satisfy Moore’s law by shrinking transistors to progressively smaller sizes and increasing the transistor density per unit area [1]. The dimension of the state-of-the-art MOSFET is now down to a few nanometers. LÄS MER

5. 4. Current-Mode Class D Power Amplifier for 2.4GHz Wi-Fi

   Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)

   Författare :Yann Jean Michael Pirot; [2023]
   Nyckelord :Power Amplifier; Wifi; Digital Power Amplfier; Class D; RFIC; Analogue; Effektförstärkare; Wifi; digital förstärkare; klass D; analog;

   Sammanfattning : Modern wireless communication techniques employed in the Wi-Fi® protocol, such as orthogonal frequency-division multiplexing exhibit analogue signals with high peak-to-average power ratio. Therefore, power amplifiers for Wi-Fi suffer from low efficiency when operating in back-off mode, away from their maximum efficiency at peak power. LÄS MER

7. 5. Design of a Differential Cross-Coupled Power LC Oscillator with ASK Modulation

   Master-uppsats, Linköpings universitet/Elektroniska Kretsar och System

   Författare :Sanjay Sarker; [2023]
   Nyckelord :Cross-coupled LC Oscillator; Amplitude Shift Keying ASK Modulator; Spiral Inductor; MIM Capacitor; Current Mirror Switching;

   Sammanfattning : Rapid growth in the field of communications industry has led to newer opportunities and challenges in the design of CMOS based monolithic integrated circuits. ASK modulators are a class of digital modulators which are known for their relative simplicity of implementation for low cost applications in the industrial and biomedical domains. LÄS MER
