Analog Devices has introduced the first in a new series of high-voltage, low-noise, zero-drift, precision operational amplifiers. The dual-channel ADA4522-2 op amp reduces reduce system noise, cost, board space, and development time by providing on-chip electro-magnetic interference (EMI) filtering and eliminating the need for calibration circuitry. The ADA4522-2 op amp operates within a supply voltage range […]

Video: supercomputing at the edge with serial RapidIO
The concept of Supercomputing at the Edge is driven from the desire to improve the management of Big Data. In Supercomputing at the Edge, we push some data center content to the edge of the access network, caching locally pertinent content closer to users and performing data analytics on streaming live data. It can be […]

Calibration of temperature sensors – I am working with two different temperature sensors. One of them is a themistor and the other is an RTD. I put them in the same place and the temperature that they both measured differed in 0.1 degrees C. However, when the temperature rises to 50 degrees then to 80 degrees, the […]
Integrated analog front-ends offer low power, low noise
The AD7124-4 and AD7124-8 AFEs from Analog Devices connect directly to all standard industrial signal sources and sensor inputs, while reducing power requirements by 40 percent over comparable devices. The power performance suits the new AFEs for an array of industrial and instrumentation applications including low power portable equipment. The highly interated AD7124-4 (four differential […]
The power of Zigbee 3.0 for smart home and IoT devices
by Cees Links As the IoT market accelerates and becomes more of a reality, the hype surrounding it becomes more intense and more confusing. It is time for a reality check to take inventory of where things really stand, and to make some assessment of where things are going. Some confusion has been cleared, some […]
Low-power RF synthesizer enhances radio sensitivity and dynamic range
Texas Instruments LMX2571 low-power wideband radio frequency (RF) synthesizer covers up to 1.34 GHz, and integrates an ultra-low-noise PLLatinum fractional-N phase-locked loop (PLL) with a multicore voltage-controlled oscillator (VCO), enabling low phase noise and spurs at 39 mA (128 mW). The device enhances radio sensitivity and dynamic range for applications such as low-power wireless communication, handheld oscilloscopes and signal […]
Power MOSFETs drive server energy efficiency
Infineon’s OptiMOS™ 5 25V and 30V product family of next-generation of Power MOSFETs in standard discrete packages feature a new class of power stages named Power Block, and in an integrated power stage, DrMOS 5×5. Megatrends such as cloud computing, IoT and social media drive an increasing demand for computing power. This is accompanied by a boost in […]
Calculating and comparing amplifier noise
I was recently presented with the problem of comparing the noise of two alternative designs that were presented to me. Normally that wouldn’t take much sorting out – a few minutes with a SPICE simulator and you would have the answer. That depends on having reliable SPICE models. The first thing I do when embarking […]
High frequency VCXO for small-cell systems
CTS Corporation, through its subsidiary, CTS Electronic Components, Inc. announces the development of a high frequency VCXO for small-cell applications available in two package sizes and output types. It is well suited for small-cell applications, such as Femto-cells, which have limited board space and demand high performance frequency control products. Available in a 7.0 x 5.0 […]

Electromagnetic field sensing – I am trying to sense an electromagnetic filed created by an iron-core coil from a distance of 12 feet. For testing, I just connect both ends of Rx coil to the scope. I get very strong signals when the Rx coil is line with either end of the Tx coil because iron core amplifies […]
