This resource provides clear explanations of how switching regulators work and how voltage boosting is achieved efficiently ...

This is simple circuit that illustrates the function of the programmable unijunction transistor. It may be quickly wired on a proto-board. The programmable unijunction transistor remains dormant until ...

A very simple but highly efficient combination lock circuit is shown in the figure. Any type of on/off switches can be used, varying from commercially available inexpensive types to more sophisticated ...

a simple regulator circuit just using two parallel transistor and potentiometer to make adjustable voltage output. a simple regulator circuit just using two parallel transistor and potentiometer to ...

If you ever work with a circuit that controls a decent amount of current, you will often encounter a FET – a Field-Effect Transistor. Whether you want to control a couple of powerful LEDs, switch a ...

We always stress how efficient electric cars are. It is important to have that in mind, and Jason Fenske recently reminded us of that with a video about the huge impact tires can have on EVs. Texas ...

Hacker [Dino Segovis] is back with yet another installment of his Hack a Week series, and it’s looking like he isn’t too worse for wear after hunkering down to face hurricane Irene. This week, it ...

Download this article in PDF format. When you connect the gate to the source of a JFET (junction field-effect transistor), it becomes a two-terminal current source. The current that will flow is ...
