[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 ...

Since CMOS has been around for about 50 years, a comprehensive history would be a book. This blog focuses on what I consider the major transitions. Before CMOS, there was NMOS (also PMOS, but I have ...

PMOS transistors are less vulnerable to substrate noise since they’re placed in separate wells; designers implement guard rings to attenuate the substrate noise propagation. However, substrate noise ...

Intel is in production with several 65-nm processors now, creating an inventory of commercial microprocessor products that will begin shipping early next year. At the IEDM conference, Intel showed die ...

The most widely used integrated circuit (IC) technology. Although the term CMOS "transistor" is widely used, it is somewhat misleading because in order to reduce power consumption, CMOS is actually ...

Dynamic random-access memory (DRAM) chips contain many other transistors besides the access transistor to enable full operation of the DRAM memory. These peripheral transistors must meet stringent ...
