Download this article in PDF format. The RF PIN diode as we know it today was invented by J. Nishizawa in 1950. Now, almost 70 years later, a new PIN diode concept—shielded-anode PIN diode (SAPIN)—has ...
In HT-PEMFCs, hydrogen is oxidized at the anode to generate protons, which are transported to the cathode through the proton conductor phosphoric acid in the high-temperature proton exchange membrane.
Hybrid water electrolysers are recent devices, which produce hydrogen or other reduction products at the cathode, while ...
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. Op amps played a critical role ...
A recent forum post reminded me of a common issue we see here at Screaming Circuits – ambiguous diode polarity marking. To start with, some diode manufactures mess with our heads where polarity ...
A classical design for directlydriving eight seven-segment LEDdisplays requires as many as 15 I/O lines.Previous Design Ideas have describedmany approaches for using a maximumnumber of LEDs with a ...
