Researchers Create Smallest Transistor Ever

Schematic of a transistor with a molybdenum disulfide channel and 1-nanometer carbon nanotube gate. (Credit: Sujay Desai/UC Berkeley) For more than a decade, engineers have been eyeing the finish line in the race to shrink the size of components in integrated circuits. They knew that the laws of physics had set a 5-nanometer threshold on the size of transistor gates among conventional semiconductors, about one-quarter the size of high-end 20-nanometer-gate transistors now on the market. But some laws are made to be broken, or at least challenged.

T-rays Will “Speed Up” Computer Memory By a Factor of 1,000

The figure shows the spin and lattice structure of thulium orthoferrite (TmFeO₃) on the left and the T-ray-induced transitions between the energy levels of thulium ions (Tm³⁺), which trigger coherent spin dynamics (memory switching), on the right. Together with their colleagues from Germany and the Netherlands, scientists at the Moscow Institute of Physics and Technology (MIPT) have found a way to significantly improve computer performance. They propose the use of so-called T-waves – or terahertz radiation – as a means of resetting computer memory cells. This process is several thousand times faster than magnetic-field-induced switching.

Keylock Switches

APEM, Vista, CA, introduced LK Series keylock switches available in nickel-plated or black overmolded barrel shutter and key. The multi-position switches are available in momentary and maintained functions, and in single or double pole configurations. They feature two-, three-, and four-position locking configuration with positive detent and multiple key-pull locations. They are rated for 4A at 125 VAC or 28 VDC, with a mechanical lifespan of 6,000 cycles at full load.

Nasa Processing Technologies Enable Advanced Computing Applications

Embedded processing technologies developed at NASA field centers are enabling the use of next-generation computer-controlled instruments and spacecraft, including SpaceCubes, integrated photonics modems, and new ways to manufacture computer components. SpaceCube ProcessorsNext-generation spacecraft instruments are capable of producing data at rates of 108 to 1011 bits per second, and both their instrument designs and mission operations concepts are severely constrained by data rate and volume. SpaceCube™ enables these next-generation missions.

Noise Analysis in Precision Analog Designs

There are articles explaining component-level noise analysis for amplifiers or for analog-to-digital converters (ADCs), but very few that explain how to budget noise or analyze noise from the system level. This paper reviews the basics of noise analysis in precision designs, relates those calculations to system-level specifications such as sensitivity, dynamic range, and resolution, and answers some of the big questions about low-noise design.
