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 ...

Electrochemical impedance spectroscopy (EIS) is used in this procedure to test the impedance in a commercial battery after connecting it two ways. An analysis of the differences in the obtained values ...

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

Specifics on ac resistance and why ACIR has become a standard measurement for Li-ions. The 1-kHz test frequency for ACIR and why it's the benchmark frequency. Comparing ACIR test vs. electrochemical ...

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 ...

As you can see, there are a number of variables and the answer is simply not that straight forward. When conducting amplifier measurements, we tend to be a bit more forgiving with receivers than multi ...

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, ...

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 ...

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