In sports, great athletes are defined by big moments. Think back to Michael Jordan hitting “The Shot” to win the 1998 NBA Finals or Maradona scoring the “Hand of God” goal to win the 1986 World Cup.

There are few technologies more fundamental to modern life than the ability to control light with precision. From fiber-optic communications to quantum sensors, the manipulation of photons underpins ...

The common emitter amplifier is one of three basic single-stage amplifier topologies. The BJT version functions as an inverting voltage amplifier. The base terminal of the transistor serves as the ...

Researchers at Purdue University have achieved a long-sought milestone, demonstrating what they call a “photonic transistor” that operates at single-photon intensities. There are few technologies more ...

Back on December 3, 2024, a Design Idea (DI) was published, “Single-supply single-ended inputs to pseudo class A/B differential output amp,” which created some discussion about using the circuit as a ...

Dynaco hasn’t made equipment in decades. Yet it’s still a name most audiophiles know off-hand. That’s because the American manufacturer left an indelible legacy on the world of hi-fi, thanks in large ...

Class D amps from $130 to $50,000—pulling more ears into hi-fi without demanding you sell a kidney. Solid tech, serious power, and none of the usual overpriced fluff. Finally, affordable doesn’t sound ...

(a) Geological units and earthquake distribution of an oceanic subduction zone. The orange shadow beneath the volcanic arc represents partially molten areas and magma channels. (b) Thermal structure ...

If you’re the sort who finds beauty in symmetry – and I’m not talking about your latest PCB layout – then you’ll appreciate this clever take on the long-tailed pair. [Kevin]’s video on this topic ...
