The following circuits are a very basic demonstration of the CMOS, NMOS and PMOS transistors in action in a circuit. Also, the following explanation is only a simple briefing of the operation, and NOT a detailed one.
A PMOS transistor is one which produces strong '0' when an input of '0' is given to it. An NMOS transistor is one which produces strong '1' when an input of '1' is given to it.
PMOS transistors are pull-up transistors and NMOS transistors are pull-down transistors. Together, PMOS and NMOS are both referred to as "pass-transistors".
A CMOS is a complimentary structure. It is a combination of both PMOS and NMOS. Whenever an input of '0' is given to the CMOS gate, the common drain produces an output of '1'. And whenever an input of '1' is given to the CMOS gate, the common drain produces an output of '0'.
For anyone who would like to explain more in detail, feel free to do so...
