LTspice simulation of the K2-W Vacuum Tube Op Amp’s design reveals the mad science that created a commercial revolution in 1950s and 1960s analog computing.
Design analysis of the K2-W Vacuum Tube Op Amp’s design and operation reveals the mad science that created a commercial revolution in 1950s and 1960s analog computing.
A book for hobbyists, engineers, Makers, and Arduino devs, "Fundamental Analog Circuits & Semiconductors,” with lab kits, successfully funded on Kickstarter.
In the first of three parts, Andy hypothesizes that the K2-W Analog Computer Op Amp’s design has some unrevealed mad science in its input-stage design.
With its minimal current consumption and 150°C operating temp, the TSU111H op amp developed by STMicroelectronics delivers an unusual combination of properties.
Wouldn’t it be great to not repeat the same amplifier application errors many new designers fall into? Read on to head off these common confusions and oversights.
In a signal-conditioning op-amp application there are a number of different approaches to take—what noise and SFDR advantages might one offer over another.
How damaging is EMI to op amps in a circuit design? And what methods are used to minimize these effects? Circuit designers may be surprised at the clever ways op amps can be used...
Intersil's Michael Steffes details how every semi company tests new analog-to-digital converter products in the lab in order to obtain data-sheet values for SFDR and SNR, then...
Michael Steffes challenges conventional approaches to Sallen Key Filter design. He says today's components and VFAs offer greater flexibility. This opinion piece links to more...
