Full-Circuit ADC Verification With Analog FastSPICE
By Mentor, a Siemens Business - 14 Oct, 2015 - Comments: 0

Analog to Digital Converters (ADCs) are critical components in high-speed, high-resolution applications where an analog or RF signal has to be processed, stored, or transported in digital form. ADC performance requirements vary by application and include resolution, dynamic range, linearity, power consumption, speed, bandwidth, SNDR (Signal-to-Noise and Distortion Ratio), and ENOB (Effective Nu... » read more

A Primer For The 802.XX Physical Layer
By Ernest Worthman - 07 Oct, 2015 - Comments: 0

This is the second installment of the 802.XX for the IoE series of articles. The first one was published in the August issue and addressed the Media Access Control (MAC) layer. In this article, we will examine the elements of the physical (PHY) layer of the 802.11 protocol stack. For reference, the protocol stack is shown in figure 1. The best designs, like everything else, are built on a so... » read more

Inside The 5G Smartphone
By Mark LaPedus - 20 Aug, 2015 - Comments: 3

Amid a slowdown in the cell phone business, the market is heating up for perhaps the next big thing in wireless—5th generation mobile networks or 5G. In fact, major carriers, chipmakers and telecom equipment vendors are all rushing to get a piece of the action in 5G, which is the follow-on to the current wireless standard known as 4G or long-term evolution (LTE). Intel, Samsung and Qualcom... » read more

Moore Memory Problems
By Brian Bailey - 09 Jul, 2015 - Comments: 0

The six-transistor static memory cell (SRAM) has been the mainstay of on-chip memory for several decades and has stood the test of time. Today, many advanced SoCs have 50% of the chip area covered with these memories and so they are critical to continued scaling. “The SRAM being used in modern systems is similar to the SRAM they were using in the 1970s and 1980s,” says Duncan Bremner, ch... » read more

Electronic Labeling Takes Off
By Emerson Hsiao - 06 Jul, 2015 - Comments: 0

One hit product for the Internet of Things (IoT) market is the electronic shelf label (ESL). The ESL is rapidly replacing the paper price labels on store shelves throughout Europe and Asia, as well as within retail giants such as Walmart in the United States. But why are retailers replacing nearly zero cost paper labels with an electronic widget that sells for on the order of $5 each (prici... » read more

Power/Performance Bits: June 2
By Jesse Allen - 02 Jun, 2015 - Comments: 0

Printing RF antennas with graphene ink Researchers from the University of Manchester, together with BGT Materials Limited, a graphene manufacturer in the United Kingdom, printed a radio frequency antenna using compressed graphene ink. The antenna performed well enough to make it practical for use in RFID tags and wireless sensors, the researchers said. Even better, the antenna is flexible, e... » read more
