# The gate to body capacitance of a MOSFET by asymptotic analysis

• Capacitance/Voltage characteristics of the MOSFET gate region at small oxide thickness show substantial variation from the oxide capacitance. We provide a numerical and analytic approach to the standard drift-diffusion equations and show how this can be used to determine analytic formulae that can be used in simulation programs such as SPICE.
