Inspecting And Testing GaN Power Semis


As demand for new automotive battery electric vehicles (BEVs) heats up, automakers are looking for solutions to meet strict zero-defect goals in power semiconductors. Gallium nitride (GaN) and silicon carbide (SiC) wide-bandgap power semiconductors offer automakers a range of new EV solutions, but questions remain on how to meet the stringent quality goals of the automotive industry. Among t... » read more

GaN Application Base Widens, Adoption Grows


Gallium nitride (GaN) is beginning to show up across a broad range of power semiconductor applications due to its wide bandgap, enabling fast-charging, very high speeds, and much smaller form factors than silicon-based chips. Unlike silicon carbide (SiC), another wide-bandgap technology, GaN is a lateral rather than a vertical device. GaN tops out at about 900 volts, which limits its use in ... » read more

Improving Reliability For GaN And SiC


Suppliers of gallium nitride (GaN) and silicon carbide (SiC) power devices are rolling out the next wave of products with some new and impressive specs. But before these devices are incorporated in systems, they must prove to be reliable. As with previous products, suppliers are quick to point out that the new devices are reliable, although there are some issues that can occasionally surface... » read more

Power Semi Wars Begin


Several vendors are rolling out the next wave of power semiconductors based on gallium nitride (GaN) and silicon carbide (SiC), setting the stage for a showdown against traditional silicon-based devices in the market. Power semiconductors are specialized transistors that incorporate different and competitive technologies like GaN, SiC and silicon. Power semis operate as a switch in high-volt... » read more

GaN Versus Silicon For 5G


The global race to launch 5G mmWave frequencies could provide a long-anticipated market opportunity for gallium nitride (GaN) as an alternative to silicon. GaN is more power-efficient than silicon for 5G RF. In fact, GaN has been the heir apparent to silicon in 5G power amplifiers for years, especially when it comes to mmWave 5G networks. What makes it so attractive is its ability to efficie... » read more

Here Comes High-Res Car Radar


A dozen or so startups are developing high-resolution radar chips that use various modulation schemes and processes, such as CMOS, FD-SOI and even metamaterials. In theory, high-resolution radar could boost the capabilities of today’s radar for cars, as well as eliminate the need for a separate LiDAR system. But the technology is still in the research stage and has yet to be proven commerc... » read more

Radar Versus LiDAR


Demand is picking up for vision, radar and LiDAR sensors that enable assisted and autonomous driving capabilities in cars, but carmakers are now pushing for some new and demanding requirements from suppliers. The automotive market always has been tough on suppliers. OEMs want smaller, faster and cheaper devices at the same or improved safety levels for both advanced driver-assistance systems... » read more
