MOSFET Gate Resistor
Explore a starting resistance for the required gate-drive transition.
Input parameters
Results
Account for driver resistance and confirm switching on hardware.
Model & assumptions
Ig ≈ Qgd/t; Rtotal ≈ (Vdrive − Vplateau)/Ig; Rexternal = Rtotal − Rdriver − Rgate.
Turn-on Miller interval estimate using Qgd at the actual operating point, not total Qg. Does not predict complete gate rise time, ringing or turn-off.
