Literature survey of the state-of-the-art for PNS stimulation circuits and the energy saving techniques. Research and development of an adaptive power supply IC to facilitate energy efficient adiabatic nerve stimulation. Collaborate with IMEC experts in PNS, analog and mixed-signal circuits to maximize your research impact. Modelling of the system in Cadence. Development and simulation of the target circuit, including drawing the schematics and layout using Cadence EDA tools. Tape-out and measurement of the chip (if time permits). Optionally, depending on results write a paper.
