2018 – Bridge 40: New approaches in the analysis and design of high performance frequency synthesizers for modern communication systems
Modern frequency synthesizer specifications (short start-up time, low cost, low power consumption, large dynamic response, adjustable within broad limits) can not be achieved only by traditional design techniques, new approaches are needed for PLL analysis, synthesis, modeling and design. Regarding PLL modeling, the system-level modeling is of high importance, short execution time of transient analyzes are sought, because it is mandatory to achieve optimization of parameters of the PLL components. “Digitization” of components in the PLL (implementation of components, which are traditionally analog circuits, with digital circuits – for example digital implementation of the loop filter) is another interesting approach, which makes it possible to digitally control the dynamic response.
2011 – IDEI 2534: New approaches in the design of multi-standard integrated radio receivers for digital radio and mobile TV: from system architecture to novel topologies and circuit solutions for the main analog blocks
This research direction explores new design methods of multi-standard integrated radio receivers for OFDM signals, in order to find new solutions and/or improve the ones currently in use.
2010 – IDEI 1027: 2.5d Modeling of Sound Propagation in Rooms and Improvement of Room Acoustical Properties Using Digital Implementations
The proposed project is an interdisciplinary one due to the needed knowledge of physics (sound propagation) and electronics (digital implementation). The main of the application is the improvement of the acoustic component of the environment in 2.5D closed spaces, where the walls are perpendicular on the floor and ceiling. The obtained results will end up in a cheap, digital solution for improvement of acoustic properties of a room.
