Postdoc or experienced researcher in radiation hardened time-to-digital conversion


Time-to-Digital Converters , making them perfectly suitable for applications involving optical Time-of-Flight measurements. Accurate time measurement is also needed in harsh radiation environments such as the readout of the many radiation detectors in high-energy physics experiments such as those at CERN in Geneva, but also for Space systems and and many terrestrial nuclear applications. Radiation impacts electronics in 2 ways: long term effects and instantaneous errors known as Single-Event Effects research position targets to address three mandatory aspects to bring the technology to a demonstrator level in order to open the roadmap for commercialization.1. Current prototypes only contain one channel, meaning only one start-stop event can be measured per chip. Typical applications demand multiple, synchronized and calibrated channels. Within this postdoctoral project, you will develop a multi-channel TDC based on the previously demonstrated TDC core.
2. The power consumption of current prototypes is relatively high for space or battery powered applications where power consumption is a bottleneck. The TDC core alone consumes 30 mW. Hence the second objective is to research improvements to reduce the power consumption to 10 mW + 5 mw/channel, making it more attractive for partners to adopt this device.
3. Finally, you will develop demonstration samples to allow customers to integrate the converters as part of their prototypes.

Each innovation will require radiation testing since new circuitry is included. We foresee both TID experiments and laser tests .


We are looking for a candidate who holds degree in Electronic Engineering or has over 5 years experience in mixed-signal chip design. Good experience and solid knowledge of CMOS integrated circuit design is required. The candidate should have a strong interest in electronics and radiation effects. Proficiency in English is required.


Besides a competitive salary and a flexible, dynamic and stimulating research environment, we offer a position in the ADVISE research group that has a leading experience in radiation tolerant integrated circuit design, collaborating closely with CERN.
