How to Evaluate Intrinsic Gate Capacitance?

Intrinsic Gate Capacitance evaluator uses MOS Gate Overlap Capacitance = MOS Gate Capacitance*Transition Width to evaluate the MOS Gate Overlap Capacitance, The Intrinsic gate capacitance formula in BJT's come from the construction of the device itself and are usually associated with its internal PN junction's. Transistors have internal capacitances that are usually not wanted and act to reduce the gain at high frequencies. MOS Gate Overlap Capacitance is denoted by C_mos symbol.

How to evaluate Intrinsic Gate Capacitance using this online evaluator? To use this online evaluator for Intrinsic Gate Capacitance, enter MOS Gate Capacitance (C_gcs) & Transition Width (W) and hit the calculate button.
