Capacitors are never 100% capacitance. Their characteristics include resistance and inductance.
Capacitors. We too often take them for granted. When it comes to high-speed circuits, capacitors can behave like resistors or even inductors, depending on the frequencies involved. When an IC need power, decoupling capacitors can help provide it, but not always.
In theory, you can increase capacitance in a circuit by placing capacitors in parallel, right? See how much you know about how capacitors behave when the frequencies are high. As always, answers appear on the last page.
Part 2 will appear next week.
1. How frequently can capacitors can be modeled as an R-L-C series network representing C, ESR (equivalent series resistance) and ESL equivalent series inductance?
