Kalkulating Gate Capacitance

Te gate- to-source capacitance (C is 1; Xi1; FLT: 0 supporti3; Xi3; gs prepari1; Xi1; FLT: 1 supporti3; Xi3;) can be estimated using thee gate oxide capacitance per unit area (C supporti1; FLT: 2 supports 3; Xi3; ox prepari1; FLT: 3 supporti3; X3;) and thee gate area (A):

Impact on Switching Speed

Capacitance feafferts the switching time of MOSFET. The time constant (τ) is given by:

kiedy R is thee resistance in thee objective. Lower capacitaince results in faster switching, which is critical in high-speed applications.
