WebThe Total Gate Charge (Qg) is the amount of charge that needs to be injected into the gate electrode to turn ON (drive) the MOSFET. The unit of Qg is the Coulomb (C), and if the total gate charge is large, it will take time to charge the capacitor necessary for turning ON … WebThe time to charge the internal source/drain capacitances is the product of the capacitance and resistance and roughly increases as the square of the number of input signals. The delivery of the output signal to more than one logic gate (Fan-Out) introduces further loading proportional to the Fan-Out. Slide 13 will give an example island living and patio
