Abstract In this work, we present the effect of self-mixing in compact terahertz emitters implemented in a 130 nm SiGe BiCMOS technology. The devices are based on a differential Colpitts oscillator topology with optimized emission frequency at the fu

This contribution presents the results of investigations performed on monolayer graphene field effect transis-tor-based (GFET-based) terahertz detectors. We have implemented three different types of planar antennae: a bow-tie, a bow-tie with transmis
