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 “backward” but ...

Dubbed BiCOM-III, TI's recently announced silicon-germanium (SiGe) complementary bipolar-CMOS manufacturing process integrates both NPN- and PNP-type bi-polar transistors. The result of this ...

Recently in material science news from China we hear that [Hailin Peng] and his team at Peking University just made the world’s fastest transistor and it’s not made of silicon. Before we tell you ...
