An inverter is an electrical circuit that consists of a PMOS and a NMOS transistor. Its task is to turn the input voltage from high potential to low potential or the other way round.

Simulate until 1e-11 s. Display the input voltage vin.p.v as well as the output voltage mp.S.v. It shows that the input voltage is inverted.
