1. 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.
