Gate Channel Capacitance in MOSFET Formulas

Gate Channel Capacitance refers to the electrical capacitance that exists between the gate electrode and the channel region of a metal-oxide-semiconductor field-effect transistor (MOSFET). And is denoted by C_g. Gate Channel Capacitance is usually measured using the Microfarad for Capacitance. Note that the value of Gate Channel Capacitance is always negative.
