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 / 2 (per flip–flop). CPD is used to determine the
no–load dynamic power consumption; PD = CPD  VCC2  fin + ICC  VCC.
