ABSTRACT:
A method and apparatus for deriving total lateral diffusion in MOS transistors includes deriving (40) a DC model. The DC model is then verified (42) with a multifinger transistor. The gate of the multifinger transistor is then isolated (44). Voltage pulses are then applied (46) to the multifinger transistor, and the current attributable to the voltage pulses is measured (48). Using the model, estimates of the total lateral diffusion are adjusted (50) until the modelled current matches the measured current. Finally, the complete and accurate AC/DC model can be used (52) by circuit designers to design various circuits that will operate as designed when implemented.
