Postdoc: Pathfinding new transistors for future energy efficient wireless applications – Heverlee, Belgium

Explore how technology innovation impacts wireless circuit design

What you will do

The deployment of millimeter-wave 5G and 6G radio systems pushes the requirements on device performance further than ever. Indeed, achieving very high-power efficiency at mmWave frequencies is critical for such application. While compound semiconductors technologies promise to meet these goals, their low-cost fabrication on a CMOS compatible platform remains challenging. Innovation is needed to design high-performant III-V/N transistors compatible with Si fabrication line. Furthermore, it is important to study the impact of new device elements at circuit level in order to optimize the technology platform.

In this postdoc, you will design new III-V/N transistors and carefully model them to operate at mmWaves in large-signal. You will perform advanced nonlinear RF characterization to feed the models and to validate them experimentally. You will use the models to simulate mmWave circuits (eg power amplifiers) and co-optimize the technology and circuit.

Type of work: 50% device characterization and modelling, 25% circuit design, 25% device design
