6. C PD 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: I CC(OPR) = C PD • V CC • f in + I CC C PD is used to determine the no–
load dynamic power consumption; P D = C
