Over the recent weeks here at Hackaday, we’ve been taking a look at the humble transistor. In a series whose impetus came from a friend musing upon his students arriving with highly developed ...

This way, 10 simulations will be run, each with a different resistance value between 1 KOhm and 10 KOhm. As usual, the different behaviors will be studied with the LTspice and ngSpice software.

In many low-power applications such as USB adaptors, cell phone chargers, and system bias supplies, the low-cost quasi-resonant/discontinuous-mode flyback converter ...

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 ...

This file type includes high resolution graphics and schematics. The spread of h FE values in a batch of transistors may be wide enough to cause unreliable performance during mass production of a ...
