Cardiff University School of Engineering is pleased to announce this fully-funded PhD studentship in electrical and electronic engineering.

Project title: Non-linear Modelling from Non-Linear Data

Designing very high efficiency power amplifiers for future mobile communication systems requires improved CAD based non-linear models. The development of accurate transistor models has proven to be a very challenging task because of the inadequacies in the RF transistor characterization tools; dynamic non-linear models being based on static or linear RF measurements. Recently there have been considerable advances in dynamic RF characterization tools, with both researchers at Cardiff University and Agilent technologies taking lead roles in their development. RF characterization systems now allow for the dynamic RF I-V waveforms measurements. Coupling with active or passive source- and load-pull systems, especially when harmonics are included, allows these RF I-V waveforms to be engineered; Waveform Engineering based characterization, exploiting load-line design and related excitation design, provides for a whole new approach to non-linear transistor modeling and model extraction. Both will be explored in this project.
