Frontend Integrated Circuits and Systems
Research foci
- RF and mmWave transceiver frontends with fully digital transmitter architectures
- Design of RF integrated circuits like LNA’s, mixers and power amplifiers
- Sampling and subsampling receivers
- Digitally assisted RF concepts like digital predistortion and self-interference cancellation
- Codesign and co-optimization of RFIC and RF frontend modules using heterogeneous / hybrid integration technologies like System-in-Package (SiP) or System-on-Module (SoM)
Research competencies
- RF and mmWave integrated circuit design with modern CMOS (SOI, FinFet) or HBT technologies
- Modern CAD and simulation hardware facilities are available with access to IC technologies via Europractice production service
- Modelling and design of RF passive components using 3D field solvers like HFSS or Momentum
- RF and mmWave PCB Design
- Lab characterization of RF and mmWave frontend building blocks on PCB and on wafer level
- Development of test solutions for transceiver frontends
Applications
- Fully digital mmWave transmitters for 5G base station massive MIMO antenna arrays
- Efficient auxiliary sensing receivers for digital pre-distortion (DPD) in phased arrays
