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 ...

If you cultivate an interest in building radios it’s likely that you’ll at some point make a simple receiver. Perhaps a ...

Designers of VCO modules can reduce the size and increase the performance of these modules with a new device that combines in a single tiny package the company's NE894 transistor for oscillator ...

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 ...

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 ...

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 ...

Figure 1: Schematic diagrams, images and device characteristics of hybrid CNT/IGZO complementary integrated circuits. Figure 2: Histograms of mobility, current on/off ratio and threshold voltage of 20 ...

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 ...
