• During the calculation of load capacitance of a 1st stage CMOS inverter, the input node capacitances, Cgs, n and Cgs, p of the 2nd stage CMOS inverter is also considered.
  ক

  True

  খ

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

  Because Cgs, n and Cgs, p are the capacitances at the input nodes

  খ

  Because Cgs, n and Cgs, p does not exist during the operation of CMOS inverter

  গ

  Because Cgs, n and Cgs, p are storing opposite charges and cancel out each other during the calculation of load capacitance
