Last time, our engineer covered the audio equipment stacks on either side of his laptop. But what do they connect to? What ...

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 ...

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

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 – ...

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 ...

Rolling into battle in a vehicle that weighs the same as ten elephants and can raze entire buildings with a single shot never gets old, but finding the best tank games that deliver in every key area ...

The WiiM AMP Ultra might have been 2025’s streaming darling, but Arcam’s A5+ reminds us that old-school Class A/B amplification still has tricks up its sleeve when driving DALI’s adorable but ...

Abstract: A previously introduced Iterative Envelope Simulator is expanded upon. The new implementation uses a Matlab-controlled ADS circuit simulator, allowing for the simulation of manufacturer ...
