Variable capacitors may be useful, but the air gap that provides their capacitance is their greatest weakness. Rather than ...

Depending upon the distance between the surface of a capacitance probe and a target source, the electrical capacitance that is formed between these two objects will vary. In an effort to improve ...

Improving the capacitance of supercapacitors requires gaining control over ion behavior inside carbon nanopores. This study ...

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 ...

As the technology node decreases, meeting inter-wire or coupling capacitance becomes extremely critical and challenging in SOC design. Shrinking technology node leads to increase in dielectric values, ...

Ferroelectrics are getting a serious re-examination, as chipmakers look for new options to maintain drive current. Ferroelectric materials can provide non-volatile memory, serving an important ...

A capacitor measured with a $100 handheld multi-meter can give a substantially different result than the same capacitor measured with a $10,000 LCR meter. That same capacitor measured with two ...

As the Semiconductor industry is growing so does the density of devices on chip. With the increasing density and decreasing spacing rules, the most significant effect that takes birth is parasitic.

Two layer PCBs are perhaps the most common in our industry. One might consider using board space on the top and bottom layers of a two layer board to create some inter-plane capacitance, between power ...

Every now and then you need to make your own capacitor. That includes choosing a dielectric for it, the insulating material that goes between the plates. One dielectric material that I use a lot is ...
