Internship | GaN PTAT and bandgap circuits

Internship | GaN PTAT and Bandgap Circuits

About this position

In Silicon technologies, PTAT and bandgap circuits are commonly used to create respectively a current proportional to temperature and a constant voltage. These currents and voltages are used to bias circuits and compensate for temperature dependence. In GaN (Gallium Nitride), these circuits are not commonly found. Hence, a realization in GaN would avoid the use of an external Silicon circuit to generate these voltages and currents.

What will be your role?

This project aims to investigate the feasibility of a PTAT and/or bandgap circuit using a depletion mode GaN HEMT MMIC technology.

The research can start by a literature search on such circuits in Silicon, GaN, or similar technologies and make an overview of possible options, advantages, and disadvantages. Followed by implementation using available technologies. It might be that measurements over temperature on existing components are needed to check the models to be used.

What we expect from you

You are in the final stages of your degree in electrical engineering or a similar degree and have a background in analogue/RF IC design. You have preferably experience with Cadence/ADS, you are pragmatic and focused on making things work. Next to technical expertise, we value communication skills and a results-driven attitude.

What you'll get in return

You want an internship opportunity on the precursor of your career; an internship gives you an opportunity to take a good look at your prospective future employer. TNO goes a step further. It’s not just looking that interests us; you and your knowledge are essential to our innovation. That’s why we attach a great deal of value to your personal and professional development. You will, of course, be properly supervised during your work placement and be given the scope for you to get the best out of yourself. Furthermore, we provide:

• A highly professional, innovative internship environment, within a team of top experts.
• A suitable internship allowance (615 euro for wo-, hbo- and mbo-students, for a full-time internship).
• Possibility of eight hours of free leave per internship month (for a full-time internship).
• A free membership of Jong TNO, where you can meet other TNO professionals and join several activities, such as sports activities, (work-related) courses or the yearly ski-trip.
• Use of a laptop.
• An allowance for travel expenses in case you don’t receive an OV-card.
