The Microelectronics group of the Electronics Department at Carlos III University (Madrid, Spain) and Infineon Technologies Austria AG invite applicants for a PhD Fellowship in Mixed-Signal Microelectronics. The research topic is edge computing architectures suitable for VCO-based MEMS readout circuits. As a practical example, the research will focus on embedding edge computing in MEMS microphones for portable or wearable devices. The target applications may be, for example, AI-based voice compression or Keyword Detection integrated with a fully featured digital microphone in the same dice. The edge computing architecture will seize the frequency-encoded data provided by a VCO-based MEMS readout circuit to implement the processing with mixed signal circuitry. The position is in the frame of a H2020 Marie Skłodowska-Curie Innovative Training Networks (ITN) action for Early Stage Researchers within the project TEVI (Time-Encoded Voice Interfaces). The position is vacant from april 2021. The grant covers 3 years of full time research (50% time in Spain, 50% time in Austria). Salary according to the Spanish and Austrian salary scales.

TEVI is aimed to propose new time-encoded techniques for low power solutions towards smart audio sensors implemented with nanometric CMOS process nodes, including raw data processing, digitization, feature extraction, compression and classification. The Early Stage Researcher (PhD student, ESR) will be assigned to the work package devoted to the design and implementation of the voice compression and classification stage. The student will carry out research tasks related to voice activation or voice keyword detection, mixed-signal microelectronics design and Artificial Intelligence, not only on his/her own, but also working with the students assigned to other TEVI’s work packages. The research will involve both Carlos III University of Madrid and Infineon Technologies Austria AG, so the student will spend half of the time in Madrid (Spain) and half of the time in Villach (Austria) supervised by PhD Advisors in each sector. Infineon technologies brings in the expertise in the MEMS sensor market, in particular in microphones, where it is a world leader. Carlos III University will bring in its expertise in VCO-based ADCs which has been transferred to MEMS microphone industry in the past through previous EU projects. The student will acquire expertise in interdisciplinary fields such as MEMS technology, signal processing, Artificial Intelligence, low power mixed signal microelectronics and transversal skills. The experience gained through this PhD program is highly appreciated by semiconductor corporations, providing him/her a valuable expertise background for a future career in the microelectronics industry.

Time-encoded signal processing has recently attracted the attention of the design community due to its excellent scalability in narrow design nodes. Time Encoding has been already tested for data converters, but its use in signal processing is currently an emerging research field. The ESR will take part in the whole process of several experimental chips, starting with the proposal of new ideas/architectures at system level, going on with the proper design at schematic level and translation to layout, and ending with experimental measurements of prototypes in the laboratory related to power efficiency, noise rejection and accuracy in pattern recognition.

Carlos III University of Madrid (Spain) was founded in 1989 and is currently ranking 16th in Europe on QS Top 50 (young universities) Under 50 2020 ranking. Carlos III University of Madrid contributes to the improvement of society through teaching of the highest quality and cutting-edge research in line with stringent international guidelines. The fellowship will take place (50%) in the School of Engineering, located in Leganes (Madrid).

Infineon Technologies is one of the leaders of the semiconductor market worldwide, providing semiconductor solutions for automotive, industrial power control, sensing and connected system sectors. Infineon Technologies ranked the 10th largest semiconductor company worldwide in sales in 2020. The fellowship will take place (50%) in the facilities of the company located in Villach (Austria).

More Information


TEVI project is aimed to train 3 creative and innovative researchers in the field of smart sensors. It will incorporate Artificial Intelligence in smart microphones in a power efficient manner, by combining novel, small, versatile and compact time-encoded circuits with innovative and robust waterproof sensors. Instead of sending raw data to a computing node (could be in the edge or in the cloud), the novel microphone will have enough computing capabilities to recognize keywords, and enough voice quality to be used in a human conversation even under water. The researchers trained in this network will be able to convert state-of-the art knowledge and ideas into new consumer products for economic and social benefit, following this example application.

As a trained researcher you will have many opportunities to develop an industrial career in any part of the world, but especially in the EU. You will be trained in chip design, sensor design, artificial intelligence techniques and other aspects of the current semiconductor industry, and you will work at Infineon Technologies as part of your assignments.

You also will be in a very good position to apply for a postdoc position in any of the top EU academic institutions. You will have a set of relevant scientific publications and international patents and a PhD Degree with International and Industry mention.
