The Limits Of Energy Harvesting


Energy harvesting, once considered an inexpensive alternative to low-power design and a way of achieving nearly unlimited power in mobile devices, has settled down to more modest expectations. This approach to generating energy through a variety of means—from solar to motion to ambient RF and even pH differences between soil and trees—has been proven to work. The problem is that it doesn... » read more

5G Heats Up Base Stations


Before 5G can be deployed commercially on a large scale, engineers have to solve some stubborn problems—including how to make a hot technology a whole lot cooler. 5G-capable modem chipsets are already on the market from Qualcomm, Samsung, Huawei, MediaTek, Intel and Apple, with some 5G service (LTE-Advanced/LTE-Advanced Pro) available in the U.S. But still mostly missing from the 5G equati... » read more

Gaps In 5G Test


Add one more industry to the long list that analysts expect 5G technology to disrupt—test. While the initial versions of this wireless technology will be little more than a faster version of 4G, concern is growing about exactly how to test the second phase of this technology, which will be based upon millimeter wave. A number of fundamental problems need to be addressed. Among them: T... » read more

VCSEL Technology Takes Off


By Kevin Fogarty and Ed Sperling Vertical cavity surface emitting laser (VCSEL) technology, a proven but mostly niche technology until recently, is suddenly a very hot commodity thanks to the introduction of facial recognition in phones and other mobile devices. VCELS primarily have been used as a low-cost way of tracking movement and transfering data in computer mice, laser printers and ... » read more

Power/Performance Bits: Jan. 14


Optical memory Researchers at the University of Oxford, University of Exeter, and University of Münster propose an all-optical memory cell that can store more optical data, 5 bits, in a smaller space than was previously possible on-chip. The optical memory cell uses light to encode information in the phase change material Ge2Sb2Te5. A laser causes the material to change between ordered and... » read more

Consolidating RF Flow for High-Frequency Product Design


Design flows are currently fragmented due to the use of poorly connected EDA tools for various design tasks. Fragmented flows are unable to meet new challenges such as increased system and circuit complexity, stricter bandwidth requirements, smaller device sizes, and changing packaging needs. In this white paper, we look at how the Cadence Virtuoso RF Solution provides a single, well-integrated... » read more

Fundamental Shifts In 2018


What surprised the industry in 2018?  While business has been strong, markets are changing, product categories are shifting and clouds are forming on the horizon. As 2018 comes to a close, most companies are pretty happy with the way everything turned out. Business has been booming, new product categories developing, and profits are meeting or beating market expectations. "2018 was indeed a... » read more

Fab Equipment Challenges For 2019


After a period of record growth, the semiconductor equipment industry is facing a slowdown in 2019, in addition to several technical challenges that still need to be resolved. Generally, the equipment industry saw enormous demand in 2017, and the momentum extended into the first part of 2018. But then the memory market began deteriorating in the middle of this year, causing both DRAM and NAND ... » read more

The Growing Promise Of Printed Electronics


Printing electronics using conductive ink rather than lithography is starting to move out of the research phase, with chipmakers now looking at how to commercialize this technology across a broad range of sensor applications. Unlike traditional semiconductors, which use tiny wires as circuits, printed electronics rely on conductive inks and often flexible films, although they can be printed ... » read more

Affordable Design With Wireless Microcontrollers


Today, we are at the peak of technology product availability with the releases of the new iPhone models, Alexa-enabled devices, and more. In the coming days, there will be numerous international consumer OEMs preparing new offerings as we approach the holiday selling season. Along with the smartphones, voice assistant enabled smart speakers and deep learning wireless security cameras, many devi... » read more
