Impact ionization in fully depleted (FD) Silicon On Insulator (SOI) n-Channel MOSFET is investigated as a function of the doping concentration. We have found that impact ionization increases with the decrease in the doping concentration and vice versa. Simulation results obtained from Sentaurus TCAD with the higher doping concentration can control the threshold voltage (Vth). Furthermore we have examined the effect of doping concentration on the transconductance (gm) and have observed that transconductance is inversely proportional of the doping concentration.
