As a service to our readers, we're providing the LTspice files used in Dr. Dyer's article on simulation of the 12AX7 and the K2-W vacuum-tube op amp. 1. The model for the K2-W is established as a ...

Extend the LM358 op-amp family’s output voltage range by cascading the op-amp with a few simple, inexpensive components.

One of the good things about simulating circuits is that you can easily change component values trivially. In the real world, ...

Abstract: This letter presents a simple and accurate interface circuit for three-wire resistive sensors based on a non-inverting amplifier and a two-phase ratiometric measurement technique. The ...

A prominent legal expert skewered President Donald Trump's move to capture Venezuelan dictator Nicolas Maduro over the weekend, a move that he described as an "inversion of our constitutional order." ...

If you've never heard of a 'DAC' before, you might be surprised to hear that you most likely use one everyday. DAC stands for digital-to-analogue converter and any device that delivers digital sound – ...

There’s hidden detail in your favourite songs and the best DACs are here to help you hear it. Whether you’re streaming on Spotify or curating your MP3 archive, a DAC is a digital-to-analogue converter ...

Aaron Hankin is currently working for Dow Jones MarketWatch. He has 10+ years of professional experience in the financial markets. The U.S. economy seems to be doing fine. Growth, for the most part ...

The objective of this project is to design, simulate, and lay out a Class-D audio amplifier using basic and discrete components only, without relying on any dedicated Class-D amplifier IC. The design ...
