Fundamental Relations in MOSFET

Electric Field
 –fundamental equation
•electric field: E = V/d–vertical field through gate oxide
•determines charge induced in channel
–horizontal field across channel
•determines source-to-drain current flow

Capacitance
–fundamental equations
•capacitor charge: Q = CV
•capacitance: C = εA/d
–charge balance on capacitor, Q+ = Q-
•charge on gate is balanced by charge in channel
•what is the source of channel charge? where does it come from?
