We break down the essential component of modern electronics—the transistor. Transistors are the building blocks behind most ...

The current flow from collector to emitter in the NPN transistor when the positive supply is applied to the base is vital variations between the NPN vs PNP. Electron mobility is a characteristic ...

In the early days, PNP ... a transistor and you’ll see it isn’t much different from an NPN except the base-emitter diode junction is reversed. As you might expect, current has to flow through ...

In an NPN transistor, a positive voltage is given to the collector terminal to produce a current flow from the collector to the emitter. In a PNP transistor, a positive voltage is given to the ...

The spin orientation of the electron was converted to an electrical charge, which was then measured using a device called a Field effect transistor, or FET. An FET can sense current changes in ...

they allow current to flow. As researchers make computer chips ever-smaller, the idea of using a type of transistor called a "single electron transistor," or SET has become increasingly appealing.
