Circuit Design 

IHP's Circuit Design department conducts research and development for silicon-based broadband and high-frequency circuits up to 500 GHz.

The Circuit Design department develops and realizes integrated microwave and millimeter-wave circuits, broadband mixed-signal circuits and circuits with high energy efficiency for communication and sensor applications.

The focus is on millimeter-wave circuits, transmit and receive circuits and frequence-synthesizer for systems with working frequencies up to 720 GHz which are designed and manufactured in IHP's current own SiGe-​BiCMOS process.

The development of broadband mixed-signal circuits concentrates on applications in fiberglass-supported and wireless broadband communication. Here, new concepts and electronic circuits for highest datarates and thus extremely large signal band width are developed.

Energy-efficient HF transmit and receive circuits are developed for their use in mobile electronic applications with battery operation. Typical application fields are communication, localization and sensor technologies. These circuits are supplemented by an intelligent, system-specific power management.

A future field of activity for the department is the development of integrated circuits for ultra-fast analog-digital and digital-analog converters with sampling rates in the GHz range. The addressed applications are in the direct synthesis of high frequency signals or in the digital signal processing of such HF signals. Research and realization of HF circuits which correspond to the state-of-the-art require a constant development of design methods and design tools. A focus is on, for example, the development of radiation-hard circuits for aerospace.
