Is that output resistance of PMOS larger than NMOS or not ?

The output impedance of either device depends on its geometry (layout dimensions). PMOS are typically lower transconductance and conductance per unit area so you just make them bigger to get the impedance to match the NMOS.

common physics let us know that there is a capacitance between any 2 accomplishing gadgets. The capacitance is a function of the dielectric consistent of the fabric between them, the area between them and the climate of the gadgets. (For sick defined shapes it must be confusing to compute the capacitance by employing hand.) So, in any MOS transistor there are capacitances between the gate and source and the gate and drain. (the region of the truly floor might exchange as a function of the utilized voltage, so the capacitances are nonlinear). i'm not sure what your truly question is, yet an proper MOS transistor with none capacitance will paintings comparable to a actual one, different than that the frequency reaction in endless.
