In the early days, PNP bipolar transistors were common, but the bulk of circuits you see today use NPN transistors. As [Aaron Danner] points out, many people think PNP transistors are “backwa… ...

OK, so I get a press release (pdf) from those wonderful folks at CamSemi, AKA Cambridge Semiconductor. It talks about their C2163 off-line switcher chip (pdf). The press release says: “…the BOM cost ...

Collector current = Emitter current – Base current = 100mA – 2 mA =98 mA Base current = Emitter current – Collector current = 100mA – 98mA = 2 mA. The condition is just reversed in the case of a PNP ...

There are numerous differences between NPN and PNP transistors, and even though both are bipolar junction transistors, the direction of current flow is the name of the game.

A 10K base resistor is used to bias an AC128 with a flashlight bulb as its collector load, and with a flying lead to the negative supply (remember this is a PNP transistor!) the bulb can be turned ...

The transistor is composed of a single layer of graphene and a single layer of molybdenum disulfide, or MoS2, which is a part of a group of compounds known as transition metals chalcogenides. The ...

The new transistor, using gallium nitride material, will enable a reduction in size and power consumption for base stations for 3G mobile phones and PHS, and wireless telecom base stations for ...
