1 AI Powered THz VLSI Testing Technology
فناوری تست THz VLSI با قدرت هوش مصنوعی-2020
Abstract—Increasing complexity of digital and mixed-signal systems makes establishing the authenticity of a chip to be a challenging problem. We present a new terahertz testing technique for non-destructive identification of genuine integrated circuits, in package, in-situ and either with no or under bias, by measuring their response to scanning terahertz and sub-terahertz radiation at the circuit pins. This novel, patent pending non-invasive nondestructive technology when merged with Artificial Intelligence (AI) engine will evolve and self-improve with each test cycle. By establishing and AI processing of the THz scanning signatures of reliable devices and circuits and comparing this signatures with devices under test using AI, this technology could be also used for reliability and lifetime prediction.

2 A Bidirectional Lens-Free Digital-Bits-In/-Out 0:57mm2 Terahertz Nano-Radio in CMOS with 49:3mW Peak Power Consumption Supporting 50cm Internet-of-Things Communication
A Bidirectional Lens-Free Digital-Bits-In/-Out 0:57mm2 Terahertz Nano-Radio in CMOS with 49:3mW Peak Power Consumption Supporting 50cm Internet-of-Things Communication-2017
A CMOS digital-bits-in/-out Terahertz (THz) nano-radio with 0.57mm2 chip area is presented in this paper. The THz operation and bidirectional transmitter/receiver (TX/RX) architecture lead to radio ultra-miniaturization for Internet-of-Things (IoT) and field-deployable sensor applications. The bidirectional THz radio is configured as a harmonic oscillator in the TX mode or as a super-harmonic super-regenerative RX in the RX mode. The TX harmonic oscillator is directly modulated by On-Off Keying (OOK) data for bits-to-THz transmitting, while an on-chip time-to-digital converter (TDC) with 25ps timing resolution measures RX oscillation start-up time for direct THz-to-bits receiving. The radio peak DC power is optimized based on link distance and data rate. It supports maximum 4.4Mb/s OOK over 50cm at 49.3mW peak DC power and 1Mb/s OOK over 17cm at 18.7mW peak DC power without using any Silicon lens.

3 Connecting in-body nano communication with body area networks: Challenges and opportunities of the Internet of Nano Things
اتصال در -بدن نانو ارتباط با شبکه های بدن: چالش ها و فرصت های اینترنت نانو اشیاء-2015
Nano-communication is considered to become a major building block for many novel applications in the health care and fitness sector. Given the recent developments in the scope of nano machinery, coordination and control of these devices becomes the critical challenge to be solved. In-Body Nano-Communication based on either molecular, acoustic, or RF radio communication in the terahertz band supports the exchange of messages between these in-body devices. Yet, the control and communication with external units is not yet fully understood. In this paper, we investigate the challenges and opportunities of connecting Body Area Networks and other external gateways with in-body nano-devices, paving the road towards more scalable and efficient Internet of Nano Things (IoNT) systems. We derive a novel network architecture supporting the resulting requirements and, most importantly, investigate options for the simulation based performance evaluation of such novel concepts. Our study is concluded by a first look at the resulting security issues considering the high impact of potential misuse of the communication links.
