  1. 1. Implementing and Testing Self-Timed Rings on a FPGA as Entropy Sources

    Master-uppsats, Linköpings universitet/Informationskodning; Linköpings universitet/Tekniska fakulteten

    Författare :Marcus Einar; [2015]
    Nyckelord :Self-Timed Rings; FPGA; Field Programmable Gate Array; Entropy Generation;

    Sammanfattning : Random number generators are basic building blocks of modern cryptographic systems. Usually pseudo random number generators, carefully constructed deter- ministic algorithms that generate seemingly random numbers, are used. LÄS MER

  2. 2. Direct Digital Pulse Width Modulation for Class D Amplifiers

    Magister-uppsats, Institutionen för systemteknik

    Författare :Stefan Stark; [2007]
    Nyckelord :PWM; Class-D; delay-line; direct digital modulation; delay element;

    Sammanfattning : Class D amplifiers are becoming increasingly popular in audio devices. The strongest reason is the high efficiency which makes it advantageous for portable battery-driven products. Infineon Technologies is developing products in this area, and has recently filed a patent application regarding an implementation of a part of the class D amplifier. LÄS MER
