Some ideal operational amplifier (often op-amp or opamp) configurations assume that the feedback resistors exhibit perfect matching. In practice, resistor nonidealities can affect various circuit ...

Sponsored by: Texas Instruments. Op amps solve most problems in analog circuit design—if you know how to use them. Here are some resources to help expand your op-amp knowledge base. Whenever you need ...

Minimizing the noise effects of electric and magnetic fields on op-amp circuits does not require a magician. A step-by-step procedure can tame such interference. Once you understand the basis of noise ...

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 source that drives high-resolution analog-to-digital converters (ADCs) sees a high-frequency ac load and a dc load of a few hundred ohms or more. Thus, a high-performance op amp with high input ...
