I wanted how to know how to determine the input capacitance of an inverter. We have many parasitic capacitances like Cgd Cgs etc. Is the ip cap dependent on this. If yes how? N how Miller's theorem has to be applied?

I got to know that ip cap is just the gate cap calculated from C=εA/d formula. No parasitics and Miller's theorem is used for digital circuits as compared with analog. Is this correct? Why is this so?
