Most ICs need to be decoupled from their power supply, usually with a 0.1uF capacitor between each power pin and ground. Decoupling is usually used to remove noise and to smooth power fluctuations.

There has been work on laying out linear capacitors on IC substrates using fractals, but we aren’t sure how that would translate into a PCB layout. We’ve seen lots of other PC trace components ...

Capacitors with unique construction and failure modes are placed on the AC line to manage EMI modes and ensure user safety.

Advanced Linear Devices has introduced a voltage balancing IC for series-connected pairs of 3.3V supercapacitors. Inside is a pair of mosfet-like devices with a sharp ‘knee’ in their voltage-current ...
