Definition of Parameters:

Substituting the equation (4) in equation (3) we get,

Differentiate the equation (2), we get

In this equation,

∆V_D=0, because V_D is a constant

This leads us to the following equation (7):

From this equation, the change in the variable value v_DS is equal to the variation in the AC value v_ds.

Since v_ds is a variable value we will get the equation (8)
