In particular, they are amorphous indium gallium oxide (a-IGZO) thin-film transistors that are being proposed for a form of DRAM, where memory density can be increased by stacking the transistors. The problem is that the resistance of the interface between metal electrodes and the IGZO channel can be excessive. It is known that introducing hydrogen […]
EPC has used GaN transistors to create a high-power Class-D two-channel audio power amplifier design. Instantiated in evaluation kit EPC9192, it is capable of pushing 700W/channel into 4Ω (or 2Ω) or 350W/channel into 8Ω. Bridging the two channels results in 1.4kW drive into 4 to 8Ω. Key components, per channel, are a pair of 200V […]
Leveraging electron beam lithography, this innovative approach promises to transform the production of OECTs, opening up new avenues for their integration into technologies such as biosensors, wearable devices, and neuromorphic systems. In an advancement in the field of organic electronics, researchers at Northwestern University have developed a new strategy for fabricating high-density and mechanically flexible […]
Generative artificial intelligence (AI) requires rapid and continuous movement of large amounts of data. In a growing number of instances, electrical input/output (I/O) connections between the ICs in chiplets are becoming a bottleneck to higher performance. Key electrical I/O performance barriers include power efficiency, bandwidth, and latency. This FAQ looks at the anticipated benefits of […]
Called UFC500, it uses silicon carbide power transistors and charges two smaller vehicles simultaneously at up to 250kW each, or one vehicle at 460kW. The exterior design meets IP55 and IK10, and cables are top-mounted to reduce the changes of damage, on a moving arm to extend reach to 4m. “Delta’s patented internal topology results […]
March 26, 2024 — Infineon Technologies AG announces the expansion of its XDP™ digital power protection controller product line with the XDP700-002, the industry’s first -48 V wide input voltage digital hot-swap controller with a programmable safe operating area (SOA) control designed specifically for telecommunications infrastructure. It boasts superior current reporting accuracy of less than […]
Artists impression over photo: “Cardiac tissue is very special,” said Jun Yao of UMass Amherst’s college of engineering. “It has a mechanical activity – contractions and relaxations that pump blood through our body – coupled to an electrical signal that controls that activity.” ‘Cardiac micro-tissue’ is the material of interest, according to the university, which […]
The round closes shortly and details can be found at: https://www.q-p-t.com/investor-overview along with a recording of a recent webinar on the technology. “QPT has a perfect combination of an amazing technology that can cut the power consumption of electric motors by 10% thereby providing a way to actively help reduce climate change and a management […]
