Variable gain amplifiers often use a mechanical potentiometer to set the gain. An example is a volume control dial. However, when the analog signal path is digitally controlled, a digital ...

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 ...

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 ...

It’s rare in 2023 for an instrument to be entirely analog, instead it’s more normal for a front-end to feed the analog-to-digital converter (ADC) in a microcontroller. Typically the front-end will do ...

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 ...

Of digital electronics, a wise man once said that “Every idiot can count to one.” Truer words have rarely been spoken, because at the end of the day, every digital circuit is really just an analog ...
