Buck regulators require an inductor that can be one of the largest components on the circuit board. By switching at 20MHz, the regulator can employ a special inductor consisting ...

For RF inductor selection, José Martos and Heinz Zenkner stress the importance of evaluating inductance, natural resonant frequency, quality, DC resistance and rated current for high-frequency ...

Using magnetic resonance in wireless power transfer tech. A stacked buck-capacitor methodology. The 3D multi-spiral inductor design. Designing and implementing an air-core embedded inductor onto a ...

We often use linear regulators in our designs. They are cheap and simple – you put the regulator chip itself on the board, add two capacitors, and get a voltage. Linear regulators are imperfe… ...

Passive components and interconnect solutions manufacturer AVX Corporation has developed a series of multilayer organic rf inductors in a 0402 case size. Providing high Q and high self resonance, the ...

Resonance. As with series circuits containing resistances, inductances, and capacitances, if the inductive reactance of a parallel circuit equals the capacitive reactance, the circuit is said to be ...

The four elements in red combine together to create a resonance at 240 kHz. In this design, 240 kHz is the conversion-combined switching frequency of the two-phase PFC. This resonance is going to ...

For an inductor-based SR, additional noise is distributed around the LC filter resonance frequency formed by the inductor and the output capacitor. ... Having a switched inductor on a PCB board is ...
