Research Bits: Dec. 5
By Jesse Allen - 05 Dec, 2022 - Comments: 0

Protonic programmable resistors for AI Researchers from the Massachusetts Institute of Technology (MIT) developed an analog deep learning processor based on protonic programmable resistors arranged in an array. In the processor, increasing and decreasing the electrical conductance of protonic resistors enables analog machine learning. The conductance is controlled by the movement of protons... » read more

By Technical Paper Link - 01 Dec, 2022 - Comments: 0

A technical paper titled "A 100-Gb/s PAM4 Optical Transmitter in a 3-D-Integrated SiPh-CMOS Platform Using Segmented MOSCAP Modulators" was published by researchers at CalTech and University of Southampton. "The resulting optimized interface between the two chips allows them to transmit 100 gigabits of data per second while producing just 2.4 pico-Joules per transmitted bit. This improves th... » read more

EDA Tools For Quantum Chips
By Marie C. Baca - 22 Nov, 2022 - Comments: 0

Commercially viable quantum computers are at least several years away, but some researchers already are questioning whether existing EDA tools will be sufficient for designing quantum chips and systems. That’s because quantum design requirements at times transcend classical rules about materials, temperature, and structure — rules that are foundational for the majority of EDA products on th... » read more

Using Silicon Photonics To Reduce Latency On Edge Devices
By Technical Paper Link - 26 Oct, 2022 - Comments: 0

A new technical paper titled "Delocalized photonic deep learning on the internet’s edge" was published by researchers at MIT and Nokia Corporation. “Every time you want to run a neural network, you have to run the program, and how fast you can run the program depends on how fast you can pipe the program in from memory. Our pipe is massive — it corresponds to sending a full feature-leng... » read more

Week In Review: Manufacturing, Test
By Karen Heyman - 16 Sep, 2022 - Comments: 0

President Biden signed an executive order on Sept. 15, limiting foreign investments in U.S. technology by "competitor or adversarial nations" that are deemed a threat to national security. In the past, the Committee on Foreign Investment in the United States (CFIUS) largely limited its actions to the sale of U.S. companies. The new directive expands that to include investments involving "U.S. s... » read more
