1. Energy-Efficient Data Converters for Low-Power Sensors
Abstract : Wireless sensor networks (WSNs) are employed in many applications, such as for monitoring bio-potential signals and environmental information. These applications require high-resolution (> 12-bit) analog-to-digital converters (ADCs) at low-sampling rates (several kS/s). READ MORE

2. CMOS Data Converters for Closed-Loop mmWave Transmitters
Abstract : With the increased amount of data consumed in mobile communication systems, new solutions for the infrastructure are needed. Massive multiple input multiple output (MIMO) is seen as a key enabler for providing this increased capacity. With the use of a large number of transmitters, the cost of each transmitter must be low.

3. Multiantenna Wireless Architectures with Low Precision Converters
Abstract : One of the main key technology enablers of the next generation of wireless communications is massive multiple input multiple output (MIMO), in which the number of antennas at the base station (BS) is scaled up to the order of tens or hundreds. It provides considerable energy and spectral efficiency by spatial multiplexing, which enables serving multiple user equipments (UEs) on the same time and frequency resource. READ MORE

4. Wave Energy Converters : An experimental approach to onshore testing, deployments and offshore monitoring
Abstract : The wave energy converter (WEC) concept developed at Uppsala University consists of a point absorbing buoy, directly connected to a permanent magnet linear generator. Since 2006, over a dozen full scale WECs have been deployed at the Lysekil Research Site, on the west coast of Sweden. READ MORE

5. Modeling and Implementation of Current-Steering Digital-to-Analog Converters
Abstract : 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. READ MORE
