NMOS conducts for the positive half cycle and PMOS for the negative, exhibiting a push–pull response, which greatly enhances the linearity of the circuit . 3.1 Circuit DesignCircuit Symbols • We represent MOSFETs with the following symbols – The book specifies nMOS vs. pMOS with arrows – I will use bubbles b/c they are easier to distinguish quickly • a digital circuit designers way of drawing symbols • These are symmetric devices and so drain and source can be used interchangeably nMOS or nFET pMOS or pFETWhen the output is high and therefore at the same level as the external PMOS drain, then no current flows (because the voltage between them is zero or very close to it). When the output is low, then a current of 5V / external PMOS gate to source resistor will flow. It is not unusual to see resistors of the order of 100k\$\Omega\$ in this use case.
