The pmos logic family uses p channel mosfets.
Since a pmos is essentially an nmos with negative voltages and current that flows in the opposite direction it might seem reasonable that pmos circuits would look like nmos circuits but with negative source voltages. So this is the setup for pretty much any p channel mosfet circuit. The schematic for the p channel mosfet circuit we will build is shown below. In the late 1960s and early 1970s pmos logic was the dominant semiconductor technology for large scale integrated circuits before being superseded by nmos and cmos devices.
