[Joe Wingbermuehle] has an interest in computers-of-old, and some past experience of building computers on perfboard from discrete transistors, so this next project, Q2, is a complete implementation ...

For years—decades, in fact—the NMOS transistor world has been on cruise control. NMOS is naturally faster and its performance has scaled better than PMOS. PMOS has had a cost advantage. But lately, it ...

Quickly learn what the difference is between PMOS and NMOS transistors in their structure and operation, and how CMOS works with the two in combination. Siliwiz, a free, browser-based, ASIC layout ...

The use of germanium instead of silicon as basic material of transistors would enable faster chips containing smaller transistors. However, a number of problems still have to be solved. Transistors ...

[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 ...
