LONDON — A series of functional 25-stage ring oscillators has been made by a team of researchers from the IBM T.J. Watson Research Center using silicon nanowire transistors with diameters down to ...

Researchers have demonstrated a new method to improve the reliability and performance of transistors and circuits based on carbon nanotubes, a semiconductor material that has long been considered by ...

In the paper, researchers examined the effect of a fluoropolymer coating called PVDF-TrFE on single-walled carbon nanotube (SWCNT) transistors and ring oscillator circuits, and demonstrated that these ...

Self-sustaining electromechanical oscillators can be built from graphene membranes that vibrate at radiofrequencies and can be tuned by a gate voltage. You have full access to this article via your ...

Oscillating circuits are the workhorses of many electronic devices. In particular, oscillating electrons emit electromagnetic waves, a mechanism that has lead to one or two applications that readers ...

The fabrication of ring oscillator structures made up from CMOS inverters demonstrates that this type of device can yield complex circuits. The silicon nanowire transistors have a hafnium-based ...

Two tuners were developed for this receiver. The more sensitive one uses tetrode transistors in the RF amplifier, mixer and oscillator. Its disadvantages lie in a much higher cost and a 12 to 14 db ...

Entries keep ticking in for the One Hertz Challenge, some more practical than others. [Pierre-Loup M.]’s One Hertz Sculpture has no pretensions of being anything but pretty, but we can absolutely ...
