As the form factor of wireless handsets, PDAs, and other portable electronics continues to shrink while their complexity level continues to grow, design engineers face an increasing number of problems ...

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 ...

Researchers at the University of Illinois, Urbana-Champaign have devised a method of combining capacitors and inductors in a tiny, 3D rolled membrane. This will save space in the electronic filters ...

This circuit for measurement of inductance and capacitance can be used to test whether the values of inductors and capacitors quoted by the manufacturer are correct. The principle used in the circuit ...

Most modern electronic devices consist of several key components: transistors, capacitors, resistors, inductors and diodes. Often, they are supplemented by additional components like crystals and ...

Amateur Radio as a hobby has a long history of encouraging experimentation using whatever one might have on hand. When [Tom Essenpreis] wanted to use his 14 MHz antenna outside of its designed ...

Only a 2.2-µH inductor and 1-µF ceramic capacitor are required for the MIC2202, a 2-MHz synchronous buck regulator that steps voltages down from a 2.3-V to 5.5-V input. Its internal power MOSFETs can ...

ISSCC: Philips’ inductor capacitor has novel output buffer Steve Bush Philips Electronics has revealed a 35.2 to 37.6GHz inductor capacitor (LC) VCO at ISSCC. Made using a 70GHz fT, 100GHz fmax, SiGe ...

Situation: You’re an IT person new to radio broadcast engineering and are given the keys to an AM transmitter site. The manager says to go out and get familiar with the equipment. The site reminds you ...
