Final answer:
The gate capacitance (C) of the input inverter is a measure of its ability to store electrical charge. It is inversely proportional to the frequency, which affects the time it takes to fully charge the capacitor. The gate capacitance is represented by the formula Xc = 2*fc², where XC is the capacitive reactance.
Step-by-step explanation:
The gate capacitance (C) of the input inverter is a measure of its ability to store electrical charge. The larger the capacitance, the greater the charge it can store and the greater the current that can flow. The gate capacitance is inversely proportional to the frequency; the higher the frequency, the less time there is to fully charge the capacitor, and so it impedes current less. In the equation Xc = 2*fc², XC represents the capacitive reactance, which is a measure of the capacitors opposition to the flow of current.
