Mos electrostatics

MOS Electrostatics

Condition is called flatband --- the voltage when this occurs

is called flatband

This state is the baseline operating case --- a capacitive

divider has one free parameter


Mos electrostatics1

MOS Electrostatics

Depletion Condition --- gate charge is terminated by charged

ions in the depletion region

Part of this region is often referred to as weak-inversion


Mos electrostatics2

MOS Electrostatics

Inversion --- further gate charge is terminated by carriers

at the silicon--silicon-dioxide interface

Mos capacitor regions

(k(Vg - VT) - Vs)/UT

Qs = ln( 1 + e )

(Y - Vs)/UT

Qs = e

Depletion (k(Vg - VT) - Vs < 0)

Inversion (k(Vg - VT) - Vs > 0)

(k(Vg - VT) - Vs)/UT

Qs = (k(Vg - VT) - Vs)/UT

Qs = e

MOS-Capacitor Regions

Surface potential moving from depletion to inversion
