How can I identify the PUN (Pull Up Network) and PDN (Pull Down Network), if shown a schematic diagram of each.
The Pull UP Network is the network implemented with the PMOS Transistor. As PMOS passes Strong logic '1' more effectively compared to logic '0' (weak 0);
The Pull DOWN Network is implemented with the help of NMOS Transistor. As NMOS passes Strong logic '0' more effectively compared to logic '1' (weak 1);
The combination of Pull up and Pull Down Network is called as "CMOS LOGIC CIRCUIT"
The Diagram for Pull UP Network and Pull Down Network is shown Below
