Look at almost any circuit, and it’s nearly sure that there will be a capacitor included in it. These two-terminal electrical components rank alongside resistors.

A subject rarely found in circuit design textbooks is the matter of nonlinear junction capacitance, especially reverse-bias junction capacitance, also called depletion capacitance. When it is ...

You can use the inherent capacitanceof an LED to make a seriesresonant boost circuit that can create avoltage large enough to light the LED.Depending on the color of the LED, youneed a voltage higher ...
