Description:

  • CMOS
  • There is constant power from one side and the gate decides if it allows electron to flow

N Type:

  • negative free-carriers (electrons)
  • Open (0) by default, Closed (1) when there is electron from gate

P Type:

  • positive free-carriers (holes)
  • Open (1) by default, Closed (0) and there will be electrons flow to gate
  • Hint: the “o” bubble of the p-type tells you that this gate wants a 0 to be turned on
