The document discusses complementary metal-oxide-semiconductor (CMOS) circuits. CMOS circuits contain both n-channel and p-channel transistors arranged so that all PMOS transistors receive input from the voltage source or another PMOS, and all NMOS transistors receive input from ground or another NMOS. The basic CMOS gates are NAND and NOR gates, from which AND and OR gates can be derived by adding an inverter to the output. CMOS is commonly used in microprocessors, microcontrollers, static RAM, analog circuits, and data converters.
