Located billions of light-years away, the "Cosmic Owl" is a pair of colliding ring galaxies spotted by the JWST. It's also an ...

Scientists have captured the moment a laser "comes to life"—and what they found challenges long-held beliefs. Using a special ...

A hybrid voltage-controlled oscillator (VCO) architecture based on a ring oscillator with inductive loading is proposed. It exhibits a better phase noise/power figure-of-merit (FOM) than a standard ...

This paper proposes a low-noise digital-to-frequency converter (DFC) for fractional-N frequency synthesis. The DFC first employs a subharmonic injection-locked ring oscillator (ILRO) to generate low ...
