In some applications, a linear amplifier is required which has different gains with regard to the polarity of the input signal. Figure 1 shows an inverting amplifier which is linear within the second ...

Whenever you need an amplifier or have a related linear-circuit design problem, most of you will turn to an op amp as a solution. Op amps are a good choice because of their universal versatility to ...

This article started because a good friend of mine dropped a Panasonic SA-XR50 switch-mode amplifier to me for some basic bench test. This article will NOT be a review of that unit, but an ...

If you’re designing a linear circuit of any kind today, it most likely involves an op amp and even an analog-to-digital converter (ADC). The op amp is your go-to device simply because it can be ...

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 open up the perennial favourite electronics textbook The Art Of Electronics and turn to the section on transistors, you will see a little cartoon. A transistor is shown as a room in which ...

This project models a basic inverting amplifier using Python code generated by an AI large language model. AI could help ...

This is an excerpt from “Self on Audio,” by Douglas Self, used with permission from Newnes Publishers, a division of Elsevier. For many years I felt that the output stages of power amplifiers ...
