The unity-gain op amp (operational amplifier) buffer circuit is routinely used to transform high-impedance inputs into low-impedance outputs. ADC (analog-to-digital converter) voltage references are ...

Analog Devices Inc. has released a new analog front end (AFE) that incorporates potentiostat and electrochemical impedance spectroscopy (EIS) functionality on a single chip to facilitate sensor ...

OBJECTIVE: To determine the accuracy of foot-to-foot bioelectrical impedance analysis (BIA) and anthropometric indices as measures of body composition in children. DESIGN: Comparison of foot-to-foot ...

When considering any new part in the signal chain, input/output impedance is usually an important spec to “bolt” the necessary signal-chain blocks together properly. For a high-speed converter, this ...

Keysight Technologies, Inc. announced shipment of its E4991B impedance analyzer, specifically designed for R&D, quality assurance and inspection engineers characterizing and evaluating passive ...

Known as EIS, Electrochemical impedance spectroscopy is an increasingly common non-destructive technique that is used to analyze and identify a material’s physicochemical properties, especially at the ...

We’ll begin by covering some of the basic mathematical relationships that everyone learns in electrical trade (or engineering) school. Unfortunately, many people seem to forget these basics in the ...

If you’ve done any amount of electronic design work, you’ll be familiar with the need for decoupling capacitors. Sometimes a chip’s datasheet will tell you exactly what kind of caps to place where, ...

The presentation of loudspeaker measurements varies wildly from manufacturer to manufacturer. This means that, without independent analysis, consumers are left comparing specifications that were ...

Over the past decade, demand for nano-electrical characterization has rapidly increased due to the continuous miniaturization of electronic devices. The semiconductor and microelectronics industries ...
