Sub-100 picosecond rise-time electronic pulse generator

Leuven | More than two weeks ago

Our work is to destroy semiconductor devices, and now we want to do it faster than ever.
Pulse generators are essential equipment in testing electronic devices like transistors and diodes. This is also true when testing for electrostatic discharge (ESD) robustness. However, compared to the usual pulse generators, for testing ESD we need both high power and high frequency pulses. For example, a 1.0 nanosecond pulse with a current of 10 A and a voltage of 500 V. This can be achieved by charging a coaxial cable and then quickly discharging it onto the device we want to test.

The limitation we face today though, is the rising time of this fast pulse, which is slower than 150 picoseconds. For proper ESD testing of future technologies we must reduce this rise time to below 100 ps and hopefully down to 50 ps.

In order to achieve this, our transmission line pulse generator needs to be re-designed. In this internship, you will look into the details of our current pulse generator design and build your own sub-100 ps prototype. To achieve this, you will need knowledge of high-frequency circuit or antenna design and modelling, measurement skills, prototyping skills and most of all, dedication.

You will work in an international team with vast experience in the ESD field, and have access to colleagues for help. Proficiency in English and good communication skills will be appreciated.
