1. Power-Efficient Continuous-Time Incremental Sigma-Delta Analog-to-Digital Converters
Sammanfattning : Over the past decade, there has been a growing interest in the devel- opment of integrated circuits (ICs) for wearable or implantable biosensors, aiming at providing personalized healthcare services and reducing the health-care expenses. In biosensor ICs, the analog-to-digital converter (ADC) is a key building block that acts as a bridge between analog signals and digital processors. LÄS MER
2. Generation, Modulation, and Detection of Signals in Microwave Photonic Systems
Sammanfattning : This thesis deals with the use of photonic technology in microwave and millimeter-wave applications. The two major parts of this work have been techniques for transmission and signal generation. LÄS MER
3. Design and evaluation of vertical cavity surface emitting lasers for microwave applications
Sammanfattning : .... 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. Multi-Level Lossless Phase Modulation in Liquid Crystals for High-Speed Spatial Light Modulators
Sammanfattning : The spatial light modulator (SLM) is a compact device that enables highly precise control of light propagation with low drive voltages and no moving parts. By imposing a certain phase modulation onto the incident lightwave, functions such as multi-beam steering, beam shaping, and air turbulence corrections can be achieved in realtime. LÄS MER
