Safe And Reliable MOSFET Operation In Bidirectional Power Switch (BDPS) Applications


The global market for battery-powered applications is rapidly growing, including power tools, service robots, light electric vehicles, and many others. The evolution of switched-mode power supply (SMPS) topologies enables designers to ensure safe charging and discharging of the equipment’s battery using bidirectional converters through the same terminal. However, to meet the safety requiremen... » read more

Hardware Root of Trust: Everything You Need To Know


As explained in our “Secure Silicon IP Webinar Series“, a root of trust is the security foundation for an SoC, other semiconductor device or electronic system. However, its meaning differs depending on who you ask. For example, the hardware root of trust contains the keys for cryptographic functions and is usually a part of the secure boot process providing the foundation for the software c... » read more

Expanding Advanced Packaging Production In The U.S.


The United States is taking the first steps toward bringing larger-scale IC packaging production capabilities back to the U.S. as supply chain concerns and trade tensions grow. The U.S. is among the leaders in developing packages, especially new and advanced forms of the technology that promise to shake up the semiconductor landscape. And while the U.S. has several packaging vendors, North A... » read more

Spin–orbit torque engineering in β-W/CoFeB heterostructures with W–Ta or W–V alloy layers between β-W and CoFeB


Abstract "The spin–orbit torque (SOT) resulting from a spin current generated in a nonmagnetic transition metal layer offers a promising magnetization switching mechanism for spintronic devices. To fully exploit this mechanism, in practice, materials with high SOT efficiencies are indispensable. Moreover, new materials need to be compatible with semiconductor processing. This study introduce... » read more

Field-free spin-orbit torque-induced switching of perpendicular magnetization in a ferrimagnetic layer with a vertical composition gradient


Abstract "Current-induced spin-orbit torques (SOTs) are of interest for fast and energy-efficient manipulation of magnetic order in spintronic devices. To be deterministic, however, switching of perpendicularly magnetized materials by SOT requires a mechanism for in-plane symmetry breaking. Existing methods to do so involve the application of an in-plane bias magnetic field, or incorporation o... » read more

Startup Funding: December 2021


Chinese startups dominated last month's fundraising, with companies from the country comprising about two-thirds of those covered in this report. In addition to the number of companies, startups from China also drew significant amounts of funding, with a display driver company and an EV battery maker each garnering around $1B and six more companies seeing rounds over $100M. Two particularly ... » read more

Manufacturing Bits: Jan. 3


Gallium oxide chips Looking to commercialize a promising ultra wide-bandgap technology in the market, Novel Crystal Technology (NCT) has developed a Schottky barrier diode based on a material called gallium oxide. NCT devised an ampere-class 1,200-V diode based on gallium oxide. A diode is a device that passes electricity in one direction and blocks it in the opposite direction. Still in R&... » read more

Power/Performance Bits: Jan. 3


Optical device integration Researchers from the University of Strathclyde, University of Glasgow, and the Australian National University propose a way to place multiple micron-scale optical devices made from different materials close together on a single silicon chip. “The development of electronics that are based on silicon transistors has enabled increasingly more powerful and flexible ... » read more

Domain-Specific Design Drives EDA Changes


The chip design ecosystem is beginning to pivot toward domain-specific architectures, setting off a scramble among tools vendors to simplify and optimize existing tools and methodologies. The move reflects a sharp slowdown in Moore's Law scaling as the best approach for improving performance and reducing power. In its place, chipmakers — which now includes systems companies — are pushing... » read more
