Energy-Efficient Floating Supply Generator Circuit for Next-Generation Neurotechnology
Master projects/internships - Leuven | Just now
Design of key analog circuit blocks for next-generation stimulation artifact-tolerant closed-loop neural interface IC.
Overview
The demand for closed-loop neuromodulation is growing due to its demonstrated medical efficacy. However, in such systems, stimulation artifacts can distort the recording channels and degrade the overall performance of the neural interface. To address this challenge, innovative stimulator and recording circuits have been developed that effectively cancel stimulation artifacts in the recording path while improving charge balancing, voltage compliance, and area efficiency in the stimulation circuit. To advance the system further and enhance power efficiency, additional research on power management circuit blocks is essential.
Internship Scope
This internship will focus on developing an innovative floating supply voltage generator circuit aimed at achieving high power efficiency while maintaining strong load regulation and fast transient response. The objective is to design a switching regulator tailored for a closed-loop neural interface system. The resulting circuit will be integrated with the existing recording and stimulator modules to enable full system integration. The student may also have a Tape-Out opportunity if the design is sufficiently prepared.
This internship provides an opportunity to work at the intersection of biomedical electronics and low-power analog circuit design, making it ideal for students with interests in analog/mixed circuit design, power management IC, and biomedical engineering.
Required skills:
- Strong background in analog circuit design.
- Good understanding of power management IC.
- Strong problem-solving skills.
- Eagerness to learn and innovate.
- Basic knowledge of PCB design and layout.
- Good communication skills.
