MOSFET Transistors
Figure 6-2 illustrates an equivalent circuit for the n-channel MOSFET transistor. The p-channel MOSFET transistor is treated similarly, but the polarities of the involved voltages are reversed.

The following equations are used to compute the relations between currents and voltages in the circuit.
There are also several capacitances between the terminals
