CMOS transceiver circuit builds a compact RFID reader News & Analysis 11/25/2003 Post a comment EM Microelectronic offers a practical circuit for an RFID card reader. The author offers instructions for configuring the circuit for read-only, read-write and passive transponder applications. Because the operation is dependent on the resonance of the RFID card with its reader, tuning capacitor selection can be critical, he advises.
CMOS dual band radio core offers digital and analog interfaces Product News 11/20/2003 Post a comment The WiLD RF is a WLAN dualband radio IP core in CMOS technology usable for development of a standalone single chip radio, either with an digital or analog interface to the modem or for integration with other functional blocks like MAC and Modem for complete 802.11a,b,g applications.
Analog Devices fourth-quarter net more than doubles News & Analysis 11/20/2003 Post a comment Analog Devices Inc. said its fiscal fourth quarter net income soared 153 percent with orders for future delivery surging to a two-year high as the chip sector recovery continued to gain momentum. The DSP and analog IC supplier exceeded analysts' consensus estimate in the three months ended Nov. 1 with revenue rising 22 percent from the year-ago quarter on broad demand from all segments of the company's operation.
White LED driver powers a 9V CCD Camera via USB News & Analysis 11/20/2003 Post a comment USB is a de facto standard in every new personal computer and/or laptop. But this doesn't come free: USB 1.0 connections only give you 5 volts. In this design note from the November issue of Planet Analog magazine, a National Semiconductor engineer shows how to wire a white LED driver to cough up the 9 volts needed to power a CCD camera.
HP iPAQ 1945: PDA packs plenty of analog Teardown 11/20/2003 Post a comment So, just how Analog is your Personal Digital Assistant? Of the roughly 600 electronic components used in the latest HP iPAQ design, only a small fraction formed the binary heart of the system, writes David Carey in this teardown report compiled for the November issue of Planet Analog magazine. Samsung, Philips, National Semiconductor, Semtech and Maxim are among the names he sees.
Analog mux parts claim reduction in signal feed-through Product News 11/17/2003 Post a comment Intersil's new MightMUX devices claim a 99 percent reduction in off-state leakage current and a 99 percent reduction in off-state signal feed-through " at least, compared with Intersil's previous-generation switches. But then, a 2-pA leakage current is respectably low.
Cognitive' radios the next step for SDR Design How-To 11/13/2003 Post a comment The future of two-way radio communication lies in the ability to use a single device to communicate as a network with other types of devices, maximize the use of limited bandwidth and harness the power of flexible and adaptive software-based protocols.
Crafting software-defined radio for 3G News & Analysis 11/13/2003 Post a comment Before software-defined radios can be fielded for cellular systems, two simultaneous and often conflicting requirements must be met: wide instantaneous bandwidth and high dynamic range in both the digital and analog domains.

What are the engineering and design challenges in creating successful IoT devices? These devices are usually small, resource-constrained electronics designed to sense, collect, send, and/or interpret data. Some of the devices need to be smart enough to act upon data in real time, 24/7. Are the design challenges the same as with embedded systems, but with a little developer- and IT-skills added in? What do engineers need to know? Rick Merritt talks with two experts about the tools and best options for designing IoT devices in 2016. Specifically the guests will discuss sensors, security, and lessons from IoT deployments.
