Abstract
The threshold voltage of a short-channel IGFET can be expressed, in relation to that for a long-channel device, asV_{T} = V_{TLC} - \alpha - \betaV_{DS}. This behavior is deduced from a charge injection model and is verified both by two-dimensional numerical simulations and by actual threshold data.
