This article showcases the advantages of an op amp loop-stability analysis method that I use myself and recommend to others. This method looks at the behavior and rate of closure of the open-loop gain ...

The very basics of operational amplifiers. Learn comparator, inverting, and non-inverting op-amp configurations. An operational amplifier, or op amp, is a dc-coupled high-gain electronic voltage ...

Solid-state device technologies, which are available to the amplifier designer, fall, broadly, into three categories: bipolar junction transistors (BJTs) and junction diodes; junction field effect ...

With so much attention on IBOC, it is appropriate to step back and review the basic principles of RF amplifiers. The radio transmitter is a collection of stages. Each stage modifies the signal in some ...

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 ...

My hands-on introduction to operational amplifiers was in 1969 while in the army as a junior scientist in the Atmospheric Science Laboratory at the White Sands Proving Grounds. We had taken a ...

If you know anything about a transistor, it’s probably that it’s a three terminal device whose output pin forms part of a potential divider whose state is dependent on what is presented to its input ...

How a paper substrate and biodegradable circuitry can be used for basic circuits. How the researchers fabricated and connected active and passive devices literally “on paper.” Details of their first, ...
