When it is connected into an amplifier circuit, as shown in Figure 1, a small amount of energy is fed back to the crystal, causing it to vibrate. These mechanical vibrations work to stabilize the ...

We’ve read a lot about oscillators, but crystal oscillators seem to be a bit of a mystery. Hobby-level books tend to say, build a circuit like this and then mess with it until it oscillates. … ...

When Marvel's Agents of S.H.I.E.L.D. went looking for a bit of jargon to explain their interdimensional portal, they happened to latch onto a very real and very important phenomenon.

Crystal Oscillator History. Back to history, ... Moreover, crystals below 30MHz are generally operated between parallel and series resonance, crystals above 30MHz but up to 200MHz are generally ...

We report the use of a silicon nanowire mechanical oscillator as a low-temperature nuclear magnetic resonance force sensor to detect the statistical polarization of 1H spins in polystyrene. Under ...

In the experiment, the first pump is tuned below the circuit’s resonance, transferring the thermal state of the oscillator into a pulse that removes the thermal energy from the drum, cooling it to ...
