The History Of CMOS

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 ...

Using Deep N Wells in Analog Design

On a conventional CMOS process (see figure 1), NMOS devices are formed in a P well or substrate connected to ground (or the most negative supply in the circuit). PMOS devices are formed in an N well ...
