We think of crystals as the gold standard of frequency generation. However, if you want real precision, you need something either better than a crystal or something that will correct for tiny errors — ...

This article describes how to design and build an adjustable, encoder-controlled, two-range sine / square wave oscillator using the SLG47004 IC. To design a simple analog sine wave oscillator (using ...

Quantum stochastic rectification is a process observed in some physical systems, which entails the conversion of random quantum fluctuations (i.e., quantum noise) and a small oscillating signal, such ...

On the figure shown, assume that it is desired to design the oscillator so that its oscillating frequency is 4 MHz. If C3 is adjusted to 300 pF and the desired feedback fraction is B=1/20, calculate: ...

The evolution of precision clocks. The tradeoffs between MEMS vs. crystal oscillators. The manufacture and cost issues involved. Almost every electronic device you can imagine depends on a precision ...

What’s the simplest audio frequency oscillator you can imagine? There’s the 555, of course, and we can think of a few designs using just two transistors or even a few with just one. But how about an ...

Almost anytime physicists announce that they’ve discovered a new particle, whether it’s the Higgs boson or the recently bagged double-charm tetraquark, what they’ve actually spotted is a small bump ...
