1. 16. Low Power Pre-Distorter Design For 5G Radio Using Machine Learning

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

   Author : Sumeeth Diddigi Kulkarni; Di Wang; [2020]
   Keywords : Technology and Engineering;

   Abstract : A Power Amplifier (PA) is an essential electronic component in all microwave and millimeter-wave applications and, more specifically, in any transmitting system where the level of input power signal needs amplification to the desired level.Linearity and high efficiency are of utmost importance in PAs.

3. 17. Ring amplifiers for high speed pipeline assisted SAR ADCs

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

   Author : Johan Holmstedt; [2020]
   Keywords : ADC SAR RAMP ring amp residue amplifier PVT; Technology and Engineering;

   Abstract : This thesis contains a review of published ring amplifier topologies. It is suggested to split the input stage of the ring amplifier into two. In this way, a robust ring amplifier can be designed without stacking the transistors in the second stage of the ring amplifier, boosting its speed properties. READ MORE

4. 18. Self-organizing Maps for Digital Pre-distortion

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

   Author : Michail Isaakidis; [2020]
   Keywords : Self-organizing maps; Digital pre-distortion; Technology and Engineering;

   Abstract : Power amplifiers are very important components in the area of wireless communications. However, they are non-linear devices and they seem to achieve high efficiency when they are operating in the non-linear regions, at the cost of being more power-consuming. In order to linearize their behavior, designers have been considering many methods. READ MORE

5. 19. The Energy Efficiency Model of a DC Motor for the Control of HEVs

   University essay from KTH/Skolan för industriell teknik och management (ITM)

   Author : JIACHENG CAI; [2020]
   Keywords : Efficiency map; DC motor; test bench; polynomial regression; K-means; Effektivetetskarta; likströmsmotorn; testbänk; polynomuttryck; K-betyder;

   Abstract : This thesis studies a DC motor for a racing hybrid electric vehicle (HEV) prototype.The development of optimization-based energy management strategies (EMS) necessitates an accurate quasi-static model of the driving motor, which includes a 2D efficiency map with the torque outputand rotating speed as the inputs.

6. 20. 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.
