What is Charge Sharing? Explain the Charge Sharing problem while sampling data from a Bus?

In the serially connected NMOS logic the input capacitance of each gate shares the charge with the load capacitance by which the logical levels drastically mismatched than that of the desired once. To eliminate this load capacitance must be very high compared to the input capacitance of the gates (approximately 10 times).
