Journal ArticleDOI
Terahertz Imaging and Sensing Applications With Silicon-Based Technologies
TL;DR: This paper reviews the progress in THz IC research and investigates several realizations of THz imaging and sensing applications with silicon-based components regarding their motivation, system performance, and challenges.
Journal ArticleDOI
Pilot study of freshly excised breast tissue response in the 300 – 600 GHz range
Quentin Cassar,Amel Al-Ibadi,Laven Mavarani,Philipp Hillger,Janusz Grzyb,Gaëtan MacGrogan,Thomas Zimmer,Ullrich R. Pfeiffer,Jean-Paul Guillet,Patrick Mounaix +9 more
TL;DR: The authors' observations suggest that the dielectric response could potentially provide contrast for breast tissue recognition within the 300 - 600 GHz range, which opens the way for silicon-based terahertz subwavelength near field imager design, efficient up to 600 GHz to address ex vivo life-science applications.
Journal ArticleDOI
Toward Mobile Integrated Electronic Systems at THz Frequencies
Philipp Hillger,Marcel van Delden,Udaya S. K. P. Miriya Thanthrige,Aya Mostafa Ahmed,Jonathan Wittemeier,Khaled Arzi,Marcel Andree,Benedikt Sievert,Werner Prost,Andreas Rennings,Daniel Erni,Thomas Musch,Nils Weimann,Aydin Sezgin,Nils Pohl,Ullrich R. Pfeiffer +15 more
TL;DR: A novel phase-locked loop concept utilizing a high-stability yttrium-iron-garnet-tuned oscillator to synthesize ultra-stable reference mmWave signals is shown, and an adaptive self-interference cancellation algorithm for THz MIMO in the digital domain based on Kalman filter theory is proposed.
Proceedings ArticleDOI
A lens-integrated 430 GHz SiGe HBT source with up to −6.3 dBm radiated power
TL;DR: In this paper, the authors presented a 430 GHz source implemented in a 0.13-µm SiGe BiCMOS technology with f T /f max of 300 GHz/450 GHz.
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.
