The transistor laser invented by scientists at the University of Illinois at Urbana-Champaign has now been found to possess fundamental non-linear characteristics that are new to a transistor and ...

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 ...

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 ...

The transistor and the PWM-switch, the core circuit of power converters, have interesting analogs. Both have three terminals, hence three configurations. They are active devices, and each has a key ...

OK, so I have an old project laptop with an IDE/PATA/slim-ATAPI optical drive bay, into which I have inserted a SATA drive caddy with a bridge board. The thing is, the caddy doesn't transfer the drive ...

The smaller electronic components become, the more complex their manufacture becomes. This has been a major problem for the ...

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 ...
