With the development towards autonomous driving vehicles increasing data traffic within the vehicle has to be considered.

New generations of automotive ethernet offering larger bandwidths need to be developed. Optical interconnects with PAM-4 modulation schemes are promising candidates. The thesis focuses on a part of the needed E/O circuits within the automotive application.

Tasks:

• - Research VCSEL driver architectures in advanced CMOS technologies
• - Schematic and layout design of a 50 GBd VCSEL driver in a 16 nm FinFET technology
• - Address special requirements for the automotive application (e.g. temperature range)
• - Post-Layout simulations and evaluation

Requirements:

• - Good understanding of circuits (e.g. ES, RFE or RFICS)

Language: German or English
