3. Monolithic Integrated Oscillators - Phase Noise Analysis and Inductor Modeling
Sammanfattning : This doctoral dissertation studies voltage controlled oscillators (VCOs) that operate at low supply voltages. Due to smaller transistor sizes and lower supply voltage ratings with every new CMOS technology, voltage headroom is diminishing. LÄS MER
4. Multi-Sensor Data Synchronization using Mobile Phones
Sammanfattning : Body sensor networking is a rapidly growing technology. Today wearable sensors are used to measure and monitor e.g. pulse, temperature, skin conductance, heart activity, and movement (through GPS or inertial measurement units). LÄS MER
5. Integrated Frequency Synthesis for Convergent Wireless Solutions
Sammanfattning : Wireless transceivers combining several standards in one unit are of key importance. In order to reach the ultimate goal of maximizing the performance-to-cost ratio of such modules, a careful study of the target application, the architecture, and the frequency planning is strongly required.
