The two types of standard transistors are PNP and NPN which differs in circuit symbols. The layers of semiconductor material used to make the transistor are denoted by the letters. To keep a straight ...

Only eight lithography masks to create a low-power custom logic chips, compared with 20+ for CMOS, is the claim of Nottingham-based fabless chip start-up ‘Search For The Next’ (SFN). As such, ...

[Dr. Cockroach]’s goal was to build a four-bit computer out of recycled and repurposed junk. The resulting computer, called IO, consists of a single 555, around 230 PNP and NPN transistors, 230 diodes ...

Zetex Semiconductors has introduced a series of miniature NPN and PNP transistors for MOSFET gate driving in latest generation power supplies. ZXTN and ZXTP transistors The first bipolars to be ...

Researchers have reported a black phosphorus transistor that can be used as an alternative ultra-low power switch. A research team developed a thickness-controlled black phosphorous tunnel ...
