In this post, we will take a gentle dive into logarithmic amplifiers—commonly known as log amps—those quietly powerful circuits that work behind the scenes to decode exponential signals and tame wide ...

Editor’s note: Here’s an oldie but goodie. EDN editors regularly field requests for copies of articles that predate our online archive, but this Design Idea from our Feb 20, 1986, issue has generated ...

In the first article about measurement systems we looked at sensors as a way to bring data into a measurement system. I explained that a sensor measures physical quantities which are turned into a ...

The term instrumentation amplifier (INA) often is misused, referring to the application rather than the architecture of the device. Historically, any amplifier that was considered precision (i.e., ...

Modeling the performance of an analog device with SPICE is one of the standard techniques used by circuit designers to perform initial characterization and performance analysis before putting together ...

Maybe you are familiar with the op-amp as an extremely versatile component, and you know how to quickly construct a huge variety of circuits with one. Maybe you even have a favorite op-amp or two for ...
