Research Bits: November 14
By Jesse Allen - 14 Nov, 2023 - Comments: 0

Solid-state thermal transistor for heat management Researchers from University of California Los Angeles created a stable and fully solid-state thermal transistor that uses an electric field to control a semiconductor device’s heat movement. It is compatible with integrated circuits in semiconductor manufacturing processes. The team’s design incorporates the field effect on charge dynamics... » read more

Manual X-ray Inspection
By Ed Sperling - 28 Aug, 2023 - Comments: 0

Increased density in advanced node chips and advanced packaging offers a way to greatly improve performance and reduce power, but it also makes it harder to inspect these devices for real and latent defects. Higher density can lead to scattering of light, and heterogeneous integration in a package means it’s not always possible to see through all materials equally. Chris Rand, product line ma... » read more

Speeding Up Design Closure
By Ed Sperling - 23 Aug, 2023 - Comments: 0

Increasing complexity and smaller process nodes make it far more difficult to achieve design closure for chips. There are more physical effects to model, including noise, cross-talk, and double switching effects, all of which can slow the design process. Solaiman Rahim, vice president of engineering for Synopsys’ EDA Group, talks about why it’s so important to analyze violations in design, ... » read more

Research Bits: August 15

Using noise for spintronics Researchers from the Institute for Basic Science built a vertical magnetic tunneling junction device by sandwiching a few layers of vanadium in tungsten diselenide (V-WSe2), a magnetic material, between top and bottom graphene electrodes to create high-amplitude Random Telegraph Noise (RTN) signals. Through the resistance measurement experiments using these devic... » read more

Reducing Noise Issues In Microcontroller Systems: Part 1
By Graeme Clark - 22 Jun, 2023 - Comments: 0

In my ideal digital world, of which I often dream, signal voltage margins are always positive, signal timing margins are always positive, power supply voltages are always within the operating voltage range, and our environment is completely benign. Unfortunately, none of us live in this ideal world, no matter how much I would like to. The real world is dirty and noisy, and the power distribu... » read more

Isolation Device Solution For Intelligent Power Module (IPM) Drive To Realize High-Accuracy Industrial Equipment In High Noise Environment
By Renesas - 22 Jun, 2022 - Comments: 0

As efforts to protect the environment have advanced, the use of inverters in industrial applications and green energy systems have continued to grow rapidly as a way to achieve low-power motor control and reduce power conversion loss. In recent years, this demand has been increasing more and more in relation to Sustainable Development Goals (SDGs). Further improvement in accuracy and downsizing... » read more

New technical paper titled "Magnifying Quantum Phase Fluctuations with Cooper-Pair Pairing" from researchers at Université PSL, CNRS, Sorbonne Université, Université Paris-Diderot, Inria de Paris, PSL Research University. Abstract "Remarkably, complex assemblies of superconducting wires, electrodes, and Josephson junctions are compactly described by a handful of collective phase degrees ... » read more

Can Analog Make A Comeback?
By Brian Bailey - 09 Jun, 2022 - Comments: 3

We live in an analog world dominated by digital processing, but that could change. Domain specificity, and the desire for greater levels of optimization, may provide analog compute with some significant advantages — and the possibility of a comeback. For the last four decades, the advantages of digital scaling and flexibility have pushed the dividing line between analog and digital closer ... » read more

Memory Bandwidth Regulation on Hybrid NVM/DRAM Platforms
By Technical Paper Link - 20 Apr, 2022 - Comments: 0

New technical paper from Shanghai Jiao Tong University Abstract "Non-volatile memory (NVM) has emerged as a new memory media, resulting in a hybrid NVM/DRAM configuration in typical servers. Memory-intensive applications competing for the scant memory bandwidth can yield degraded performance. Identifying the noisy neighbors and regulating the memory bandwidth usage of them can alleviate th... » read more
