Final thesis: Analog design and layout of HV-DAC interface for electro-optic devices
Developing innovative technology solutions and bringing them to application - that is our goal at the Fraunhofer Institute for Photonic Microsystems IPMS. With our expertise in the development of photonic microsystems, related technologies including nanoelectronics and wireless communication solutions, we create - in flexible and interdisciplinary teams - technologies for innovative products in a wide range of markets such as automotive, industrial and aerospace.
Fraunhofer IPMS has been developing IP cores as well as complete digital and analog ASICs for many years. Electro-optic modulators (EOMs) play an important role in influencing photons in opto-integrated systems. Electro-optic modulators work based on Pockels effect which modifies the refractive index of certain optical waveguides thereby influencing the photon carried by it.
As a part of the data acquisition and control unit of a mixed signal electro-optical integrated circuit (IC) a High Voltage-Digital to Analog Converter (HV-DAC) is required. The high voltage, high speed and scalability are key challenges to control an EOM array.
In this work, DAC architectures will be explored and compared. The selected architecture will be designed as schematic and validated in Virtuoso. In the next step, the DAC layout will be done in a selected target technology and the DAC is characterized by post-layout simulation. Finally, HV-DAC layout design will be done, together with a previously designed HV amplifier, and the HV-DAC is characterized by post-layout simulation.
What you will do
- Digital-Analog-Converter architecture exploration and literature survey
- Analog design and validation in Cadence Virtuoso
- Layout design
- Post layout simulation
- Documentation of results and findings
The tasks can be carried out as topic for a Bachelor, Diploma or Master thesis.
What you bring to the table
- Studies in the field of electrical engineering or a similar field of studies
- Basic knowledge of analog integrated design
- Experience working in Cadence Virtuoso environment and associated simulation tools
- Basic know-how of analog layout design
- Experience in Layout in modern ASIC nodes will be an added advantage
- Independent and self-organized way of working and interested in gaining experiences in an international environment
- Good German or good English skills
