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 ...

In this interview Dr Tim Ashworth, Applications Manager at Zurich Instruments talks to AZoM about the latest innovations in Impedance Analyzers. Tim explains the key challenges in the world of ...

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 ...

RCD uplift is a measurable and predictable phenomenon that affects no-trip loop impedance testing. When left unaddressed, it ...

Currently, the rebound hammer is widely used for estimation of compressive strength of concrete as general testing method. Although rebound hammer has made great contribution for compressive strength ...

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 ...

Most radio engineers today will recall uncomfortable evenings and cold nights spent in dog houses making antenna impedance measurements, or worse, still trying to balance a laboratory model GR bridge ...

PHOENIX, AZ—Picotest.com, a developer and marketer of high-resolution test and measurement equipment, has released the J2161A, 2-Way Wideband Active Splitter. This accessory enables the 2-port shunt ...

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 always enjoy a [FesZ] video and we wonder if the “Z” stands for impedance? That’s the topic of his latest video series: measuring impedance with LTSpice. Of course, he also does his usual thorough ...
