Working Student: Design of Frequency Upconverter in CMOS Technology for D-band Applications

Developing innovative technology solutions and bringing them to application - that is our goal at the . 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. The research focus is design and implementation of a high performance frequency upconverter in 22-nm FDSOI CMOS technology targeting D-band (110 - 170 GHz) applications. The key milestone is to develop a suitable circuit architecture including the key components such as mixer and frequency multiplier. This position is to support the RF design team at CNT on the design level.   Be part of change Frequency upconverter design for D-Band applications: You design and optimize frequency upconverters in 22-nm FDSOI CMOS technology, targeting high performance and reliability for D-band (110-170 GHz) applications. Circuit analysis and optimization: You analyze and optimize circuit components using advanced simulation tools such as Cadence Virtuoso to ensure efficient functionality and robust design. Electromagnetic simulation: You perform electromagnetic simulations of the circuit layout using Ansys HFSS or PathWave ADS to optimize the design's performance  Layout preparation for fabrication: You create detailed layouts for fabrication, adhering to design specifications and ensuring manufacturability and compliance with foundry requirements. Design-rule checking (DRC) and LVS validation: You conduct comprehensive design-rule checking (DRC) and layout vs. schematic (LVS) validation to ensure the layout aligns with the foundry's rules and the schematic design.   The tasks can also be implemented as part of a master's thesis.   What you contribute Academic Background: You have an academic foundation in Electrical Engineering with a focus on RF engineering. Knowledge of transistor technologies, system-level design, and RF circuit simulation is highly desirable. Technical Skills: You possess practical experience with advanced circuit simulation software, including electromagnetic (EM) simulation tools such as ANSYS HFSS and PathWave ADS. A solid understanding of RF design and the ability to quickly grasp new theories and concepts from literature are essential. Problem-Solving: You demonstrate resilience and a structured approach to debugging and resolving issues in simulations. Patience, perseverance, and readiness to test multiple solutions and design iterations are critical qualities. Creativity and Flexibility: You actively contribute original ideas based on your expertise and promote them for further discussion. You balance creativity with flexibility, following conventional approaches when directed by supervisors. Fast Learning Ability: You are capable of quickly understanding new theories and concepts from literature, adapting them effectively to your work. Communication Skills: You listen attentively to feedback and suggestions from supervisors and respond thoughtfully and constructively to drive project success. Language Skills: You are proficient in written and spoken English (C2 level) and possess basic German language skills to support effective collaboration.   What we offer We offer you an exciting task and valuable insights into the methods and procedures of a modern high-tech research institute.
