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.
