12.2.1 NMOS & PMOS Behaviour

12.2.1. NMOS and PMOS Behavior

NMOS Switch Example

Verilog

Circuit Diagram:

Operation:

- control = 0: NMOS OFF → y = Z (floating)

- control = 1: NMOS ON → y = 0 (pulled to ground)

PMOS Switch Example

Verilog

Circuit Diagram:

Operation:

- control = 0: PMOS ON → y = 1 (pulled to VDD)

- control = 1: PMOS OFF → y = Z (floating)
