1. 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
2. Studies on CMOS Digital-to-Analog Converters
Sammanfattning : In this thesis we present an overview and study on digital-to-analog converters (DAC), mainly for communications applications. Especially, we look at some digital subscriber line (DSL) specifications and communication over twisted-pair channels. LÄS MER
3. On High-Speed Digital-to-Analog Converters and Semi-Digital FIR Filters
Sammanfattning : High-speed and high-resolution digital-to-analog converters (DACs) are vital components in all telecommunication systems. Radio-frequency digital-to-analog converter (RFDAC) provides high-speed and high-resolution conversion from digital domain to an analog signal. RFDACs can be employed in direct-conversion radio transmitter architectures. LÄS MER
4. Massive Multi-Antenna Communications with Low-Resolution Data Converters
Sammanfattning : Massive multi-user (MU) multiple-input multiple-output (MIMO) will be a core technology in future cellular communication systems. In massive MU-MIMO systems, the number of antennas at the base station (BS) is scaled up by several orders of magnitude compared to traditional multi-antenna systems with the goals of enabling large gains in capacity and energy efficiency.
