CMOS
(
Complementary
Metal
Oxide
Semiconductor) Pronounced "
c-moss." The most widely used integrated circuit design. It is found in almost every electronic product from handheld devices to mainframes. CMOS uses PMOS and NMOS transistors wired together in a balanced fashion that causes less power to be used than NMOS or PMOS transistors by themselves. The first transistors were bipolar, which are still used when higher power is required. CMOS and bipolar are also used in combination for many applications. See
MOSFET,
FET and
bipolar transistor. See also

A Note from the Author
Years ago, we had a kitten at the beach that we named CMOS. When we introduced the cute feline to people while the surf was slapping the sand, everyone thought it was such an appropriate name for a beach cat. "Sea Moss." Of course! However, when we told them her name stood for "complementary metal oxide semiconductor," they didn't come around much any more.
