Why does input capacitance cause delay in MOSFET?

The gate voltage is made positive to turn ON the MOSFET. When the gate voltage has applied the gate to source capacitance Cgs (gate source capacitance) starts charging. During this period, the drain current increases to its full value of ID because of that the MOSFET is fully turned ON.

How to Calculate MOSFET Turn ON Time?

MOSFET Turn ON Time calculator uses Turn ON Time = MOSFET ON Delay Time+Rise Time to calculate the Turn ON Time, The MOSFET turn ON Time formula is defined as the time needed for charging the MOSFET internal capacitance. Turn ON Time is denoted by T_on symbol.
