Theme 2: Sensors, Circuits and Systems
We are studying various spintronic and magnetic sensors including Hall effect, Giant Magnetoresistance (GMR), Tunnelling magnetoresistance (TMR), nuclear magnetic resonance (NMR) and fluxgate devices for various applications ranging from point-of-care diagnostics to wearables.
Our work focuses on CMOS-spintronic sensing interfaces circuits, allowing them to be manufactured as integrated Analog Front-End (AFE) including various circuits building blocks e.g. analogue-to-digital converters (ADC) and DC-DC converters for low-power and high-speed electronics systems.
We are designing CMOS analog and mixed signal circuits for various applications e.g. biomedical and cryogenic electronics (Cryo-CMOS).
