[Scott Harden] has been working through a design for a variable inductor to use as a PTO, or permeability tuned oscillator. What you see above is the most recent fruit of these efforts. The variable ...

Figure 1: Superconducting qubit–oscillator circuit. Figure 3: Selection rules and transmission spectrum around the symmetry point. In conclusion, we have experimentally achieved deep strong coupling ...

This 1 Hz and 2Hz generator or oscillator is built with 4060 as an oscillator and a 14 bits counter. To obtain a 1Hz signal after 4060 we use 1/2 4013. This circuit provides a rectangular voltage with ...

Another great crystal oscillator circuit with BB139, a 2-nd harmonic quartz crystal and one BF214 transistor. So, the Q quartz is half of the desired transmitter frequency, L1 has 24 turns, 0.08mm Ø ...

Said to consume 10 times less power than comparable circuits, the EM7604 CMOS crystal oscillator is intended for use with a 32.768 kHz tuning fork crystal as a low-frequency clock oscillator with no ...

The first computer circuit to be built on a single molecule has been unveiled by researchers in the US. It was assembled on a single carbon nanotube, a standard component of any nanotechnologist's ...
