1. 1. Investigation of Analog Calibration Systems for Spurious Tone Suppression in Frequency Triplers

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

   Author : Cristian Alexandru Ghihanis; Barath Copparam Santhanakrishnan Sudarsan; [2023]
   Keywords : Delay-Locked Loop; DLL; Edge-Combining; EC; EC DLL; Edge-Combining Delay-Locked Loop; spurious tone calibration; spurs calibration; spurious tones compensation; spurs compensation; Technology and Engineering;

   Abstract : 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. READ MORE

3. 2. Design of a 16 GSps RF Sampling Resistive DAC with on-chip Voltage Regulator

   University essay from Linköpings universitet/Elektroniska Kretsar och System

   Author : Pontus Thomsson; Cyrus Seyed Aghamiri; [2021]
   Keywords : DAC; LDO; RDAC; 16GSps; 12-bit; Digital-to-Analog Converter; Low-Dropout Regulator;

   Abstract : Wireless communication technologies continue to evolve to meet the demand for increased data throughput. To achieve higher data throughput one approach is to increase the bandwidth. One problem related to very large bandwidths is the implementation of digital-to-analog converters with sampling rates roughly in the 5 to 20 GHz range. READ MORE

4. 3. Characterization of Passive Intermodulation Distortion in MultiBand FDD Radio Systems

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

   Author : Tomás Soares da Costa; [2019]
   Keywords : ;

   Abstract : Intermodulation distortion (IMD) is a phenomenon that results in generation of spurious distortion signals when two or more signals of different frequencies pass through a nonlinear system. In general, IMD occurs in active circuits of a radio system, however, passive wireless components such as filters, transmission lines, connectors, antennas, attenuators etc. READ MORE

5. 4. A Differential Measurement Probe with High Common Mode Rejection

   University essay from Lunds universitet/Industriell elektroteknik och automation

   Author : Björn Franzén; [2018]
   Keywords : Common mode rejection; Fiber-optic measurement probe; Current Sensing; High voltage measurements; Optical isolation; Technology and Engineering;

   Abstract : Measuring signals with high frequency common mode components are typically prone to measurement errors due to low common mode rejection at high frequencies. The purpose of this master thesis is to design a measurement probe that presents sufficient common mode rejection to measure current on high voltage motor drives directly at the switching stage, before filtering.

6. 5. Highly linear attenuator and mixer for wide band TOR in CMOS

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

   Author : Hind Abdalslam Abdallah Dafallah; [2016]
   Keywords : TOR; Attenuator; Mixer; Linearity; PA; Technology and Engineering;

   Abstract : In this thesis work, a highly linear passive attenuator and mixer were designed to be used in a wide-band Transmission Observation Receiver (TOR). The TOR is a low IF receiver that accepts RF frequencies from 2GHz to 7GHz, and produces corresponding IF bandwidths of 280MHz to 990MHz respectively, using low side LO injection. READ MORE
