Wide Band Gap—The Revolution In Power Semiconductors


New government regulations and industry standards are leading companies to adopt wide bandgap (WBG) power solutions, both to reduce their carbon footprint and to meet increasing demand for higher power systems aimed at electric vehicles, renewable energy, datacenters, and other markets. The automotive industry is one of the biggest markets driving demand for WBG power devices. The European U... » read more

A Novel Design Method of Highly Efficient Saturated Power Amplifier Based On Self-Generated Harmonic Currents


A novel design method without requiring the special harmonic termination circuit for a highly efficient power amplifier (PA) is proposed. The proposed PA is driven into saturated operation, from the linear to knee region, by adjusting the only fundamental load, and the saturated operation induces self-generated harmonic currents. The current and voltage waveforms can be shaped easily by the har... » read more

MicroLEDs: The Next Revolution In Displays?


Flat-panel display technology is exploding on several fronts as more screens are required for more devices. But one type of display is generating an enormous amount of buzz in the market—microLEDs. Dozens of companies are working on micro-light emitting diodes (microLEDs), a technology that promises to provide better and brighter displays than current solutions in the market. Apple, Facebo... » read more

SiC Demand Growing Faster Than Supply


The silicon carbide (SiC) industry is in the midst of a major expansion campaign, but suppliers are struggling to meet potential demand for SiC power devices and wafers in the market. In just one example of the expansion efforts, Cree plans to invest up to $1 billion to increase its SiC fab and wafer capacities. As part of the plan, Cree is developing the world’s first 200mm (8-inch) SiC f... » read more

Power/Performance Bits: May 14


Detecting malware with power monitoring Engineers at the University of Texas at Austin and North Carolina State University devised a way to detect malware in large-scale embedded computer systems by monitoring power usage and identifying unusual surges as a warning of potential infection. The method relies on an external piece of hardware that can be plugged into the system to observe and m... » read more

Week In Review: Manufacturing, Test


Trade More trade news: "The Trump administration is hiking duties on $200 billion worth of Chinese products to 25% from 10%," according to CNBC. The following is attributed to Gary Shapiro, president and CEO of the Consumer Technology Association (CTA), in response to President Trump’s plan to increase tariffs on $200 billion worth of Chinese imports to 25%: “The president is seeking a bet... » read more

5G Heats Up Base Stations


Before 5G can be deployed commercially on a large scale, engineers have to solve some stubborn problems—including how to make a hot technology a whole lot cooler. 5G-capable modem chipsets are already on the market from Qualcomm, Samsung, Huawei, MediaTek, Intel and Apple, with some 5G service (LTE-Advanced/LTE-Advanced Pro) available in the U.S. But still mostly missing from the 5G equati... » read more

How Do I Know? A Machine Told Me So


More than 375 years ago, René Descartes wrote “I think, therefore I am.” And “Think” has been a slogan used by no less a technology giant than IBM for more than a century. The thought process has been a defining aspect of humanity since our beginning. But now technologists are working to imbue that capability into machines through artificial intelligence. Programming computers is no... » read more

Connected Cars: From Chip To City


As the automotive industry moves closer to autonomous vehicles, ecosystem players are focusing on the infrastructure pieces needed to make autonomous technology a reality for the first adopters, which are most likely commercial fleets. Vehicle-to-infrastructure (V2I or v2i) is a communications model that allows vehicles to share information with the components that support a country's hi... » read more

Manufacturing Bits: April 10


Higher power GaN Imec and Qromis have announced the development of a new gallium nitride (GaN) substrate technology that enables power devices at 650 volts and above. GaN is an emerging technology for power semiconductor applications. Based on a GaN-on-silicon technology, GaN-based power semis operate at 650 volts and above. In simple terms, the buffer layers between the GaN device and the ... » read more
