1. 21. Design of a 12-bit 200-MSps SAR Analog-to-Digital converter

   University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

   Author : Luca Ricci; [2020]
   Keywords : ;

   Abstract : The Successive Approximation (SAR) Analog-to-Digital converter is one of the most energy-efficient A/D converter. In this thesis, the development of a SAR ADC in a 28-nm CMOS technology based on charge redistribution is presented. READ MORE

3. 22. Hybrid Beamforming Design for Full-Duplex mmWave Relaying Systems

   University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

   Author : Zhe Wu; [2020]
   Keywords : mmWave; full-duplex; hybrid beamforming; self-interference cancellation; OMP; fast ADMM; convergence; mmwave; fullständig duplex; hybridstrålformning; självförstörande annullering; OMP; snabb ADMM; konvergens;

   Abstract : With the tremendous growth in the mobile data traffic, the demand for highdata rate is increasing rapidly, and higher frequency resources shall be exploredto alleviate the congestion in the overcrowded spectrum, thus, the millimeterwave (mmWave) frequency resource ranging from 30 GHz to 300 GHz has beenrecognized as a nature fit for the fifth-generation (5G) and beyond network. Tocompensate the severe path-loss in the mmWave band as well to realize theefficient transmissions by applying the low-cost architecture, it is of intereststo investigate the beamforming schemes with large-scale antenna arrays andthe full-duplex (FD) relaying strategy, which are indispensable in the operationof directional signal transmission and the efficient spectrum utilization inthe mmWave transmission, respectively.

4. 23. System Model of an Ultra-LowPower Fluorescence Detection Micro-Device

   University essay from Linköpings universitet/Elektroniska Kretsar och System

   Author : Yuanyuan Xue; [2020]
   Keywords : ;

   Abstract : This thesis aims to explore the power consumption limits of Complementary Metal-Oxide-Semiconductor (CMOS) fluorescent biosensors that meet the demand, a Matlab-based calculator is designed, in which users can input required system parameters (such as LED power and noise) to observe the minimum power consumption of each basic component and the constraints of the transimpedance amplifier: cut-off frequency, signal- to-noise ratio, dynamic range, etc. Thereby to provide a reference range for the next level designs of each component in the detection system.

5. 24. Wireless electromyogram system

   University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

   Author : Andreas Dunca; Hoang Anh Quoc Nguyen; [2020]
   Keywords : Venous thromboembolism; VTE prevention; Electromyogram; Embedded system; Muscle sensor; Venös tromboemboli; Förebygga VTE; Elektromyografi; Inbyggda system; Muskelsensor;

   Abstract : Venous thromboembolism (VTE) is one of the most common cardiovascular diseases. KTH and its academic and industrial partners intend to develop a system to combat VTE by forcing movements of inactive muscles. An important part of this system is a unit that can sense muscular activity over time. READ MORE

6. 25. Time Synchronization for Full-Duplex Communications

   University essay from Lunds universitet/Institutionen för elektro- och informationsteknik

   Author : Ziyu Liu; Aamer Al-Hamwi; [2019]
   Keywords : Time Synchronization; In-band full-duplex; self-interference cancellation; Technology and Engineering;

   Abstract : In-band full-duplex has emerged as an attractive solution for significantly enhancing the throughput of wireless communication systems by doubling the spectrum efficiency compared to conventional half-duplex systems. However, the existence of self-interference is a significant barrier to operate full-duplex systems. READ MORE
