1. Om implementation of maximally fast wave digital filters
Sammanfattning : An approach to design and implement fixed-function digital filters using bit-serial arithmetic is proposed. The resulting implementations are maximally fast, i.e., the maximal sample frequency fmax is equal to the upper bound on the sample frequency given by the recursive parts of the algorithm. LÄS MER
2. Complexity and Power Reduction in Digital Delta-Sigma Modulators
Sammanfattning : A number of state-of-the-art low power consuming digital delta-sigma modulator (ΔΣ) architectures for digital-to-analog converters (DAC) are presented in this thesis. In an oversampling ΔΣ DAC, the primary job of the modulator is to reduce the word length of the digital control signal to the DAC and spectrally shape the resulting quantization noise. LÄS MER
3. Design of Integrated Building Blocks for the Digital/Analog Interface
Sammanfattning : The integrated circuit has, since it was invented in the late 1950's, undergone a tremendous development and is today found in virtually all electric equipment. The small feature size and low production cost have made it possible to implement electronics in everyday objects ranging from computers and mobile phones to smart prize tags. LÄS MER
4. Modeling and Implementation of Current-Steering Digital-to-Analog Converters
Sammanfattning : Data converters, i.e., analog-to-digital converters (ADCs) and digital-to-analog converters (DACs), are interface circuits between the analog and digital domains. They are used in, e. LÄS MER
5. On Reduction of Substrate Noise in Mixed-Signal Circuits
Sammanfattning : Microelectronics is heading towards larger and larger systems implemented on a single chip. In wireless communication equipment, e.g., cellular phones, handheld computers etc. LÄS MER
