[Kevin Darrah] wanted to make a simple 3.3V regulator without using an integrated circuit. He wound up using two common NPN transistors and 4 1K resistors. The circuit isn’t going to beat out a cheap ...

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 ...

The schematic diagram shows an audio stage with a common-collector circuit. This does not damp the tuned circuit, but instead actually increases its response. This yields good sensitivity and ...

(Nanowerk Spotlight) Organic semiconductors have long held promise for enabling deformable electronic devices that can be manufactured at low cost and high volumes using printing techniques. However, ...

Shockley had continued his semiconductor work, and in 1948 patented the modern junction transistor. Three years later, Bell Labs demonstrated part number M1752 ...
