High precision is the key to the future of robotics
As far back as 1925, Scottish inventor John Logie Baird successfully transmitted the first recognisable image using a device he called the Televisor. However, the technology was held back until after 1947 when John Bardeen, Walter Brattain and William Shockley of Bell Laboratories co-invented the transistor.
'Green' electronic materials produced with synthetic biology
Scientists at the University of Massachusetts Amherst report in the current issue of Small that they have genetically designed a strain of bacteria that spins out extremely thin and highly conductive wires made up of solely of non-toxic, natural amino acids. Researchers led by microbiologist Derek Lovely say the wires, which rival the thinnest wires known to man, are produced from renewable, inexpensive feedstocks and avoid the harsh chemical pro...
Implementation and signoff tools achieve certification
The implementation and signoff tools ofCadence Design Systems have achieved certification on the Intel 3rdgen 10nm tri-gate process for customers of Intel Custom Foundry. Intel Custom Foundry utilised a PowerVR GT7200 graphics processing unit (GPU) from Imagination Technologies as part of the certification process.
Analogue compiler could enable simulation of organisms
A transistor, conceived of in digital terms, has two states: on and off, which can represent the 1s and 0s of binary arithmetic. But in analogue terms, the transistor has an infinite number of states, which could, in principle, represent an infinite range of mathematical values. Digital computing, for all its advantages, leaves most of transistors’ informational capacity on the table.
GaN FET driver is claimed to be the world's fastest
Peregrine Semiconductor has announced what it claims to be the word’s fastest GaN FET driver, the UltraCMOS PE29100. Designed to drive the gates of a high-side and a low-side GaN FET in a switching configuration, the PE29100 delivers the industry’s fastest switching speeds, shortest propagation delays and lowest rise and fall times to AC/DC converters, DC/DC converters, class D audio amplifiers and wireless charging applications.
60V N-channel MOSFET offers industry's best resistance
Texas Instruments has introduced a 60V N-channel FemtoFET power transistor that provides the industry's lowest resistance, 90% below traditional 60V load switches. Reducing power loss in end-systems. The CSD18541F5 is offered in a tiny 1.53x0.77x0.35mm silicon-based package that has an 80% smaller footprint than load switches in SOT-23 packages.
Silicon chips could be replaced by molecular electronics
Technion researchers have developed a method for growing carbon nanotubes that could lead to the day when molecular electronics replace the ubiquitous silicon chip as the building block of electronics. The findings are published this week inNature Communications.Carbon nanotubes (CNTs) have long fascinated scientists because of their unprecedented electrical, optical, thermal and mechanical properties, and chemical sensitivity.
Fast voltage regulators improve data centre energy efficiency
Heterogeneous Integrated Power Stage (HIPS) will be implemented by Sarda in UTAC’ 3D SiP (system-in-package), based on ECP technology from AT&S, to improve data centre energy efficiency.
Material has memory function resembling synapses
Our brain does not work like a typical computer memory storing just ones andzeroes: thanks to a much larger variation in memory states, it can calculate faster consuming less energy. Scientists of the MESA+ Institute for Nanotechnology of the University of Twente (The Netherlands) now developed a ferro-electric material with a memory function resembling synapses and neurons in the brain, resulting in a multistate memory. They publish their result...
'Origami' reshapes DNA's future
Ten years after its introduction, DNA origami, a fast and simple way to assemble DNA into potentially useful structures, is finally coming into its own. In a recent paper in Journal of the American Chemical Society, a team of researchers used the technique to program DNA to form large, 2D honeycombs and tubes. Because those structures are assembled biologically, rather than by conventional chemical reactions, they have very precise and repeatable...
