Electronically-variable capacitors, whether used for T&M or in an end circuit, usually have a maximum capacitance of a few hundred picofarads, and a limited adjustment range. This Design Idea ...

Variable capacitors may be useful, but the air gap that provides their capacitance is their greatest weakness. Rather than deal with the poor dielectric properties of air, some high-end variable ...

The first British commercially available high-vacuum variable capacitors have been announced by the English Electric Valve Co. So 64 years ago, started a story in Electronics Weekly’s edition of March ...

Emerging applications like 5G communications and evolving automotive requirements such as for advanced driver-assistance systems (ADAS), autonomous driving, and on-board chargers for electric vehicles ...

Switched-mode power supplies (SMPS) and low dropout (LDO) regulators are found in electronic systems. Critical SMPS requirements include a stable output voltage with load current, good temperature ...

Tantalum surface-mount capacitors have gained widespread favor for bulk decoupling use in both conventional and switch-mode power supplies (SMPSs) since their introduction more than 20 years ago.

Variable capacitors may be useful, but the air gap that provides their capacitance is their greatest weakness. Rather than deal with the poor dielectric properties of air, some high-end variable ...
