New ferroelectric material sandwiched between GaN gates, makes the transistor switch faster and more efficient, through ...

These electrons are zippy and help the transistor switch rapidly, but they also tend to travel up towards the gate and leak out. To prevent them from escaping, the device can be capped with a ...

The reactance of an inductor and a capacitor is a function of frequency. A circuit containing resistance, inductance, and capacitance is resonant at one specific frequency. If that frequency is close ...

A complex impedance measurement provides information about the local capacitance and resistance. The dielectric constant and the dopant density in semiconductors may be calculated using local ...

Reducing the parasitic capacitance between the gate metal and the source/drain contact of a transistor can decrease device switching delays. One way to reduce parasitic capacitance is to reduce the ...

Recently, a research team led by Professor Huang Xingjiu at the Institute of Solid-State Physics, the Hefei Institutes of Physical Science of the Chinese Academy of Sciences, has proposed a novel ...

The advantages of Hf0.5Zr0.5O2 The negative capacitance is a direct result of the intrinsic energy barrier between two stable polarization states of the ferroelectric layer, he says. In regular ...

Figure 3 Op-amp gain topologies To understand how the input capacitance can affect the design choices for these types of circuits, let’s first discuss a method of stability analysis that will clearly ...

Energy saving: artist’s impression of the gate material with negative capacitance. (Courtesy: Ella Maru Studio) By exploiting a curious effect called negative capacitance, researchers have designed a ...
