Why is Ericsson a good place to work?

Ericsson enables communications service providers to capture the full value of connectivity. The company's portfolio spans Networks, Digital Services, Managed Services, and Emerging Business and is designed to help our customers go digital, increase efficiency, find new revenue streams, and create new user experiences. Ericsson's investments in innovation have delivered the benefits of telephony and mobile broadband to billions of people around the world ensuring our solutions - and our customers - are at the forefront of innovation. We support networks that connect more than 2.5 billion subscribers. With over 100,000 employees and customers in 180 countries, we combine global scale with technology and service leadership. 40 percent of the world's mobile traffic is carried over an Ericsson network. And, our Technology for Good and Connect to Learn programs include creating technology that makes it easier to save lives, feed societies, bring technology to emerging markets and connectivity to remote areas, and grow businesses and prosperity.

At Ericsson, we give our employees the freedom to think big and navigate their career, on a global scale. We create technology that helps others, from helping people enjoy their favourite content to helping people recover from natural disasters by enabling better communications between rescue workers. Your ideas and innovations can turn into achievements that impact society and change the world, creating new connections, new possibilities, and new capabilities. We find that Ericsson is at its best when we bring together the diverse skills of our people. Working across business areas, across cultures, across geographical borders, across technical disciplines. More often than not, across ground-breaking solutions. Next generation technology can be staggeringly complex. But the simpler it is to use; the more people benefit from it. Join us and help build technology that makes it simple to connect with information, business, societies, and each other.

Our Exciting Opportunity

Are you up for the challenge to develop next generation integrated circuits for our continued leadership in 5G development? At Ericsson, we are now investing heavily in the future 5G technology where cutting-edge development is key. Please find our two Master Thesis opportunities below within the area of analog and mixed signal ASIC design!

The location of the thesis: Linköping, Sweden.

Master Thesis 1 - Comparator Design for High-Speed ADCs

In radio base stations, high-speed analog-to-digital converters (ADCs) are required to handle wide band signals. A critical sub-circuit in ADCs is the comparator which performs the basic function of comparing two voltages. A challenge of comparator design is to obtain a very short decision time while keeping other key parameters such as power consumption, hysteresis, offset, and noise sufficiently low. In this thesis work you will study the latest state-of-the-art comparator architectures, implement some of them in schematics and compare them by simulations with aid of optimization tools.

You will

  • Do literature surveys to gain familiarity with high-speed comparators.
  • Do transistor schematic implementation of a few selected architectures from the literature studies.
  • Verify basic operation of the selected architectures by simulations. Initial device sizing to make the different comparators functional.
  • Optimize the selected architectures with help of optimization tools. Compare the results of the different architectures.


The thesis will be concluded with a result presentation for the Ericsson team

To be successful in the role you must have

  • Education in electrical engineering, computer engineering or similar with interest in full custom integrated circuit design.
  • Analog/digital circuit design basics (relevant coursework).
  • Experience in transistor schematic design (Virtuoso IC) and circuit verification (Spectre simulator).
  • Custom layout design experience (preferred but not mandatory).


Master Thesis 2 - ASIC Process Variation Sensor Design

For high-performance CMOS integrated circuits, process variations during fabrication cause device parameters to change, e.g., transistor mobility, threshold voltage etc. Such variations pose a challenge to achieving the desired performance while maintaining power efficiency. On-chip process variation sensors provide information on the transistor behavior in the fabricated chip. Based on this information, specific circuit parameters (for e.g. the supply voltage) can be tuned in order to achieve the desired performance or lower the power consumption.

You will

  • Do literature survey to gain familiarity with process sensors architectures. Identify the state-of-the-art in this domain.
  • Do transistor schematic implementation of an all-digital process sensor which features compact area and low design complexity.
  • Verify the functionality and robustness of the process sensors using transistor simulation tools.
  • Based on availability of time and process design kit used, perform layout design of the process sensor.
