A Note from the Editor



What’s Up With Digital Downconverters – Part 1

Regardless of the end application, whether it is communications, aerospace/defense, or instrumentation, the frequencies of interest are pushing higher into the RF and microwave spectrum. Many current radio receiver architectures contain analog down conversion stages that translate an RF or microwave frequency band down to an intermediate frequency for baseband processing. This article explains how the new generation of RF ADCs with an integrated Digital Down Conversion function, eliminates the need for analog down conversion stages and allows the spectrum in the RF frequency domain to be directly converted down to baseband for processing.


New RF DAC Broadens Software-Defined Radio Horizon

On the transmitter side of a communications system, a new class of high-speed digital-to-analog converter, called an RF DAC, has the ability to directly synthesize RF signals without a conventional analog up conversion analog radio chain. In conjunction with the JESD204B high speed serial interface that enables practical management and transfer of output data, RF DACs enable conventional radio designs to be made more efficient than with previous generations of RF class or IF-class DACs. This article explores in detail ADI’s new RF DAC architecture, applications, and performance.

Going Full Tilt

I would like to improve the accuracy and repeatability of tilt measurements using the ADIS16209 inclinometer. Can I use several of these sensors in parallel to improve the accuracy?



Electromagnetic Flowmeters: Design Considerations and Solutions

There are multiple industry trends driving the need for a new flow measurement architecture, such as wastewater treatment plants, chemical/pharma plants, food and beverage processing, and pulp and paper production. These applications increasingly have the need to measure flow in the presence of high levels of solids, which is not easily achieved by most analog flow technologies. This articles focuses on the design considerations of implementing an electromagnetic flowmeter architecture as a solution that simplifies system design, improves performance, and lowers cost and power.

Op Amp Input Overvoltage Protection: Clamping vs. Integrated

In some applications, a situation may occur in which the inputs of an op amp get driven by voltages that exceed the level of the supply voltages—this is called an overvoltage condition. Overvoltage can result in certain aspects of the op amp’s electrical performance being shifted beyond its data sheet guaranteed limits; it can even cause permanent failure of the device. The challenge then is to add overvoltage protection (OVP) circuitry at the input of the op amp without adding errors that result in a loss of system precision. This article compares and contrasts two approaches to input overvoltage protection.
