While measuring the output load capacitance Cgs, n and Cgs, p is not considered. Why?

Correct Answer: Because Cgs, n and Cgs, p are the capacitances at the input nodes
Cgs, n and Cgs, p are gate to source capacitances of nMOS and pMOS transistors in CMOS inverter. They are measured at input node. Therefore they are not considered for calculation of load capacitance.
