Using the TDA7052A audio amplifier to generate a five octave, linear in pitch voltage-controlled oscillator (VCO).

The D’Agostino New-Generation Momentum Z Monoblock Amplifier is priced a $125,000 USD and available through Authorized Dealers Internationally, Canada, Mexico, and the US.

Reading an article about the first transistorized Hi-Fi amplifier, [Netzener] got the itch to make one. But what to use for the starting point? Enter an old Radio Shack P-Box stereo amplifier kit.

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

Abstract: Recently we presented the S-AMP approach, an extension of approximate message passing (AMP), to be able to handle general invariant matrix ensembles. In this contribution we extend S-AMP to ...

Abstract: This article presents the first application of a digital-intensive intrinsically linear digitally controlled class-E technique in a Doherty configuration. By careful nonlinear segmentation ...
