Analog mixed-signal radio chips

The Barkhausen Institut (BI) develops analog mixed-signal radio chips as a foundation for innovative and trustworthy hardware solutions. The RF Design Enablement group oversees the entire process - from circuit design and high-frequency-optimized antenna engineering to physical implementation (layout design) using state-of-the-art semiconductor technologies within the Silicon Saxony microelectronics cluster. Chip packaging and printed circuit board (PCB) co-design is precisely tailored to meet the demanding requirements of analog high-frequency applications.
Following fabrication, comprehensive functional testing and system-level evaluations are carried out in the BI laboratories. These enable detailed analysis of signal integrity and component interoperability within the overall system in advance, reducing potential errors and improving development quality.

Analog mixed-signal radio chips developed at BI are used wherever high-precision signal processing and maximum reliability are essential - such as in safety-critical communications, advanced sensing, and industrial automation.
In addition to circuit design and fabrication, the BI’s analog chips emphasize a holistic understanding of signal processing within the overall system. State-of-the-art system simulations and parametric testing make it possible to identify and precisely optimize complex interactions in analog mixed-signal design at an early stage. This ensures the high reliability and precision of the chips - qualities that are indispensable in safety-critical applications.
