6. CPD is defined as the value of the internal equivalent capacitance which is calculated from the operating current consumption without load.

Average operating current can be obtained by the equation: ICC(OPR) = CPD VCC fin + ICC. CPD is used to determine the no−load dynamic

power consumption; PD = CPD VCC2 fin + ICC VCC.
