MOSFETs and IV Curves
Introduction
Various VDS
voltages across MOSFETs will give you an IV curve where you can see the
cutoff, saturation region, and linear regions of the plots.
Methods
ElectricVLSI
was used to build the NMOS and PMOS transistor, and simulated using
LTSpice after passing appropriate design checks.
Results
PMOS and NMOS
schematics and layouts were created, and all passed DRC, NCC, and well
checks. The simulations were ran and the various IV curves were plotted
for each transistor.
