Faculty of Information Technology and Electrical Engineering, Circuits and SystemsThe University of Oulu is a multidisciplinary, international research university, with about 4000 employees who produce new knowledge based on high-standards research and provide research based education to build a more sustainable, smarter, and more humane world. The University of Oulu community has about 17,000 people in total. Our northern scientific community operates globally and creates conditions for the emergence of innovations.We are looking for an applicant forThree-year doctoral researcher position in integrated circuit design for time-resolving CMOS single-photon avalanche diode (SPAD) arraysto join us in the Circuit and Systems (CAS) Research unit at the Faculty of Information Technology and Electrical Engineering, University of Oulu.CAS has been engaged in integrated circuit (IC) design-including analog, digital, and mixed-signal-since the late 1980s. Over the years, it has designed hundreds of ICs for various applications across several groups within CAS. One group's primary focus has been the development of pulsed time-of-flight techniques and integrated circuits for precise photon detection. The group has concentrated on developing time-resolving CMOS SPAD arrays for time-gated Raman spectroscopy and time-domain diffuse optics in the past decade.The group consists of four doctoral researchers and six senior/postdoctoral researchers.About the jobAs a doctoral researcher, you will be part of the research group in the field of time-resolving CMOS SPAD array integrated circuit design. You will participate in an IC design research project in which an integrated circuit for time-gated Raman spectroscopy will be designed using CMOS technology with SPADs as a library component. You will be designing circuit blocks, e.g., Time-to-Digital Converters (TDC), Delay-Locked Loops (DLL), digital readout and control logic, and the whole time-resolving CMOS SPAD array, including the I/O pad ring.You will also measure the functionality of the designed and fabricated IC, including characterization of the timing performance of the IC and Raman spectroscopy tests with the Raman setup available at the CAS research unit. For the measurement, the FPGA circuit/microcontroller unit design will also be part of your task to operate the designed IC fully. As a doctoral researcher, you will publish the results in scientific conferences and journals. In addition, 30 credit points of studies are required. Finally, you will write your doctoral thesis and have a public defense within three years.What we offer?
