For over a century now, radio amateurs have made tuned circuits using a coil of wire and a variable capacitor. In recent decades the supply of variable capacitors has dwindled, as SDR technology has ...

A tuned circuit formed by a capacitor and an inductor is a familiar enough circuit, and it’s understood that it will resonate at a particular frequency. As that frequency increases, so the size of the ...

SAN DIEGO--(BUSINESS WIRE)--Peregrine Semiconductor Corporation, a fabless provider of high-performance radio-frequency (RF) integrated circuits (ICs), today announced availability of the ...

Researchers created flexible integrated circuits precisely tuned by illuminating an organic polymer with ultraviolet light. This work may allow for inexpensive electronics to be incorporated into ...

VARIABLE condensers are now so commonly employed in radio receivers to tune circuits including a constant inductance that the use, some years ago, of variable inductances or variometers with fixed ...

While LCR meters are readily available at reasonable cost, they do not measure the Q of an inductor. This circuit enables you to measure the Q of inductors with the aid of an RF signal generator. A ...

Scientists have created a toolkit for synthetic biologists who need to precisely tune the input and output levels of genetic circuits. Rice University scientists have created a toolkit for synthetic ...

The content discusses the principles of capacitance, inductance, and resistance in electrical circuits, particularly in alternating current (AC) systems. It explains how capacitors and inductors ...

Last month's column covered the behavior of electrical components connected in series and demonstrated that when a voltage is applied across a series circuit, the current through each component is the ...

Osaka, Japan – Researchers from SANKEN (The Institute of Scientific and Industrial Research) at Osaka University and JOANNEUM RESEARCH (Weiz, Austria), have shown how exposing an organic polymer to ...
