Week In Review: Auto, Security, Pervasive Computing


Automotive Verizon and Cisco demonstrated a C-V2X network for autonomous driving in Las Vegas that avoids using costly physical roadside units to extend radio signals. Instead, Verizon and Cisco say their test proved that Verizon’s LTE network and public 5G Edge with AWS Wavelength, together with Cisco Catalyst IR1101 routers in connected infrastructure, were adequate to meet the latency nee... » read more

EDA On Cloud Presents Unique Challenges


Discussions about cloud-based EDA tools are heating up for both hardware and software engineering projects, opening the door to vast compute resources that can be scaled up and down as needed. Still, not everyone is on board with this shift, and even companies that use the cloud don't necessarily want to use it for every aspect of chip design. But the number of cloud-based EDA tools is growi... » read more

Silicon Thermo-Optic Switches with Graphene Heaters Operating at Mid-Infrared Waveband


Abstract "The mid-infrared (MIR, 2–20 μm) waveband is of great interest for integrated photonics in many applications such as on-chip spectroscopic chemical sensing, and optical communication. Thermo-optic switches are essential to large-scale integrated photonic circuits at MIR wavebands. However, current technologies require a thick cladding layer, high driving voltages or may introduce h... » read more

A novel multimodal hand database for biometric authentication


Abstract "Biometric authentication is one of the most exciting areas in the era of security. Biometric authentication ideally refers to the process of identifying or verifying the user through physiological and behavioral measurements using security processes. Multimodal biometrics are preferred over unimodal biometrics due to the defensive nature of multimodal biometrics. This research intr... » read more

Clocks Getting Skewed Up


At a logical level, synchronous designs are very simple and the clock just happens. But the clocking network is possibly the most complex in a chip, and it's fraught with the most problems at the physical level. To some, the clock is the AC power supply of the chip. To others, it is an analog network almost beyond analysis. Ironically, there are no languages to describe clocking, few tools t... » read more

Blog Review: March 30


Ansys' Shawn Carpenter takes a look at the continuing impact of potential interference with aircraft's radar altimeters on the roll out of the 5G C-band and the testing that will be needed to enable 5G C-band service towers to begin operating near airports by July. Siemens' Harry Foster points to an increase in the number of engineers working on automotive ASIC projects and the growing compl... » read more

The Foundations Of Computational Electromagnetics


Maxwell’s Equations can be expressed in multiple variants – there are integral and differential versions in both frequency and time domains, along with quasi-static and full-wave forms. Their elegance is evident upon sight yet for only the simplest systems are there known solutions. Thus, without assumptions to simplify the math and/or system under study, it is frequently impossible to full... » read more

Nonvolatile Capacitive Crossbar Array for In-Memory Computing


Abstract "Conventional resistive crossbar array for in-memory computing suffers from high static current/power, serious IR drop, and sneak paths. In contrast, the “capacitive” crossbar array that harnesses transient current and charge transfer is gaining attention as it 1) only consumes dynamic power, 2) has no DC sneak paths and avoids severe IR drop (thus, selector-free), and 3) can be f... » read more

Qubits made by advanced semiconductor manufacturing


Abstract: "Full-scale quantum computers require the integration of millions of qubits, and the potential of using industrial semiconductor manufacturing to meet this need has driven the development of quantum computing in silicon quantum dots. However, fabrication has so far relied on electron-beam lithography and, with a few exceptions, conventional lift-off processes that suffer from low yie... » read more

The speed limit of optoelectronics


Abstract "Light-field driven charge motion links semiconductor technology to electric fields with attosecond temporal control. Motivated by ultimate-speed electron-based signal processing, strong-field excitation has been identified viable for the ultrafast manipulation of a solid’s electronic properties but found to evoke perplexing post-excitation dynamics. Here, we report on single-photon... » read more
