  2. 1. Implementation of digit-serial filters

    Author : Magnus Karlsson; Mark Vesterbacka; Lars Wanhammar; Wlodek Kulesza; Viktor Öwall; Linköpings universitet; []
    Keywords : ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Implementation; CMOS; Low Power; High Speed; Wave Digital Filter WDF ; FIR filter; Signal processing; Signalbehandling;

    Abstract : In this thesis we discuss the design and implementation of Digital Signal Processing (DSP) applications in a standard digital CMOS technology. The aim is to fulfill a throughput requirement with lowest possible power consumption. READ MORE

  4. 2. ADC modeling from a system perspective and design of RF-sampling radio receivers

    Author : Kalle Folkesson; Linköpings universitet; []
    Keywords : ;

    Abstract : The analog-to-digital converter (ADC) is the key component in many modem electronic systems. Examples are wire-line communication systems such as digital subscriber line modems, wireless communication systems such as radio receivers, and sensor systems such as military radar. READ MORE

  5. 3. Integrated Lumped Element and Ferroelectrically Tunable Microwave Components

    Author : Dan Kuylenstierna; Chalmers University of Technology; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; lumped; Passive element; metamaterial; periodic structure;

    Abstract : This thesis treats the development of passive circuits for increased integrationlevel in microwave front-ends. The subject is approached from twodifferent directions. On the one hand, emerging materials for microwaveintegrated circuits are studied. On the other hand, novel circuit topologiesare synthesized. READ MORE

  6. 4. Digitally controlled analog multiply-accumulate units

    Author : Mattias Duppils; Linköpings universitet; []
    Keywords : TECHNOLOGY; TEKNIKVETENSKAP;

    Abstract : This thesis is about digitally controlled analog multiplier-accumulator (MAC) units and their utilization in communications applications. These units are implemented as switched-capacitor circuits, designed with switches (MOS transistors), capacitors (MOS transistors), and amplifiers (MOS transistors); using a CMOS technology.
