Power/Performance Bits: Jan. 27


Improving batteries By digging into the complex science behind the formation of dendrites that cause lithium-ion batteries to fail, research by Purdue University engineers could bring safer, longer-lasting batteries capable of being charged within minutes instead of hours. According to the researchers, dendrites form on anode electrodes and may continue to grow until causing an internal sho... » read more

System Bits: Jan. 20


Nanodiamonds are quantum’s best friend Purdue University researchers have demonstrated a new way to enhance the emission of single photons by using "hyperbolic metamaterials," in a step they say could be used in developing quantum computers and communications technologies. Optical metamaterials harness clouds of electrons called surface plasmons to manipulate and control light. The team p... » read more

Boosting silicon solar cells According to Stanford researchers, stacking crystalline perovskites onto a conventional silicon solar cell dramatically improves the overall efficiency of the cell. The researchers reminded that silicon solar cells dominate the world market, but the power conversion efficiency of silicon photovoltaics has been stuck at 25 percent for 15 years. One inexpensive wa... » read more

Productivity And The IoT


The market for devices that connect almost everything to the Internet of Things is projected to explode, creating opportunities for companies that haven’t been traditional chip developers to decide to start developing devices. Semiconductor Engineering sat down to discuss this topic with Jack Guedj, corporate VP of Tensilica products at Cadence; Bill Neifert, CTO at Carbon; Marc Evans, direct... » read more

Higher Frequencies Mean More Memory


As SoCs get more complex, whether due to higher frequencies or adding more functionality, there is a spillover effect on bandwidth, [getkc id="22" kc_name="memory"] and power. There is no simple way to just turn up the clock frequency in a complex [getkc id="81" kc_name="SoC"]. That relatively straightforward objective will likely require more power domains, more cores, more ways to move sig... » read more

Designing For Automotive


As cars include an increasing amount of electronics and electronics subsystems, the number of design challenges involving reliability, cost and power are on the rise. “Reliability tops the list of concerns for the design team because when you put these electronics in, you must know if they are going to operate efficiently by themselves," said Aveek Sarkar, vice president of product enginee... » read more

CES: THE Must-See Auto Show?


Power is such a huge concern for the automotive sector these days, it was not too much of a surprise to hear from Atrenta CTO Bernard Murphy that while at CES, he heard many folks suggesting that the experience that can only be called ‘CES’ may be the new must-see auto show. He observed that car companies are paying attention to surveys showing that a significant percentage of buyers vi... » read more

System Bits: Jan. 13


Quantum computational circuits MIT researchers have built an array of light detectors sensitive enough to register the arrival of photons and mounted them on a silicon optical chip, which could be critical components of quantum computing devices. They pointed out that single-photon detectors are notoriously temperamental. For example, of 100 deposited on a chip using standard manufacturing ... » read more

Glass instead of crystals Since today's lithium-ion batteries are not good enough if our future energy system is to rely on electrical power, researchers around the world are continually looking to improve capacity and energy density. To this end, ETH Zurich researchers have developed a type of glass that can be used as an electrode material in lithium-ion batteries. ETH researchers discove... » read more
