Journal ArticleDOI
A 1 k-Pixel Video Camera for 0.7–1.1 Terahertz Imaging Applications in 65-nm CMOS
R. Al Hadi,Hani Sherry,Janusz Grzyb,Yan Zhao,Wolfgang Forster,Hans M. Keller,Andreia Cathelin,Andreas Kaiser,Ullrich R. Pfeiffer +8 more
TL;DR: A 1 k-pixel camera chip for active terahertz video recording at room-temperature has been fully integrated in a 65-nm CMOS bulk process technology and includes row and column select and integrate-and-dump circuitry capable of capturing terAhertz videos up to 500 fps.
Journal ArticleDOI
A 0.53 THz Reconfigurable Source Module With Up to 1 mW Radiated Power for Diffuse Illumination in Terahertz Imaging Applications
Ullrich R. Pfeiffer,Yan Zhao,Janusz Grzyb,Richard Al Hadi,Neelanjan Sarmah,Wolfgang Forster,Holger Rucker,Bernd Heinemann +7 more
TL;DR: This paper presents a high-power 0.53 THz source module with programmable diversity to adjust the brightness and the direction of light to obtain the desired diffuse lighting conditions in THz imaging applications.
Proceedings ArticleDOI
14.5 A 0.53THz reconfigurable source array with up to 1mW radiated power for terahertz imaging applications in 0.13μm SiGe BiCMOS
Ullrich R. Pfeiffer,Yan Zhao,Janusz Grzyb,Richard Al Hadi,Neelanjan Sarmah,Wolfgang Forster,Holger Rucker,Bernd Heinemann +7 more
TL;DR: Like imaging at visible light, active THz imaging would greatly benefit from incoherent artificial light sources to adjust brightness, phase/frequency, and the direction of light to obtain the desired lighting conditions.
Journal ArticleDOI
A 128-Pixel System-on-a-Chip for Real-Time Super-Resolution Terahertz Near-Field Imaging
Philipp Hillger,Ritesh Jain,Janusz Grzyb,Wolfgang Forster,Bernd Heinemann,Gaëtan MacGrogan,Patrick Mounaix,Thomas Zimmer,Ullrich R. Pfeiffer +8 more
TL;DR: This paper presents a fully integrated system-on-a-chip for real-time terahertz super-resolution near-field imaging that features both an analog readout mode and a lock-in-amplifier-based digital read out mode, as well as a biometric human fingerprint.
Proceedings ArticleDOI
High data-rate communication link at 240 GHz with on-chip antenna-integrated transmitter and receiver modules in SiGe HBT technology
Janusz Grzyb,Pedro Rodriguez Vazquez,Neelanjan Sarmah,Wolfgang Forster,Bernd Heinemann,Ullrich R. Pfeiffer +5 more
TL;DR: In this article, a high data-rate communication link at 240GHz with highly-integrated direct-conversion quadrature transmitter and receiver modules implemented in 130nm SiGe HBT technology with ft/fmax of 350/550 GHz is presented.
