A high-density real-time 1024-pixel terahertz near-field imager in 130-nm SiGe BiCMOS

Terahertz near-field imaging enables high-resolution biomedical and material characterization by combining the non-ionizing nature of terahertz radiation with sub-wavelength spatial resolution. However, the scalability of existing solid-state near-field imagers is fundamentally limited by shared illumination scheme...
