Electronics textbooks will tell you that a non-inverting opamp normally cannot be regulated down to 0 dB gain. If zero output is needed then it is usual to employ an inverting amplifier and a buffer ...

In the last Circuit VR we looked at some basic op amp circuits in a simulator, including the non-inverting amplifier. Sometimes you want an amplifier that inverts the signal. That is a 5V input ...

Operational amplifiers (commonly called op amps) are a ubiquitous building block for designing electronic circuits. Today, these devices are fabricated as small integrated circuits, but the concept ...

This file type includes high-resolution graphics and schematics when applicable. Most data-acquisition systems with wide dynamic range need a method of adjusting the input-signal level to the ...

Members can download this article in PDF format. In designing an input stage for an analog-to-digital converter (ADC), engineers choose a particular amplifier, assign a target gain, and note the ...
