PMOS (or pMOS)
From The Glossary of Digital Photography
An abbreviation for positive metal oxide semiconductor. Also known as MOS and MOSFET. A type of field-effect transistor. One of the most popular MOSs in digital is the CMOS or complementary metal-oxide semiconductor. MOS is the most widely used type of transistor currently used in digital circuits. These transistors are basically miniature switches and are widely used in digital cameras and computers. See CMOS: MOSFET: MOS
