WebApr 10, 2024 · This scaling down also eliminates many stray capacitances that are present in the overall device. Ultimately increasing the speed of operation. But when the channel length is scaled down to the order of the depletion layer, a certain number of non-ideal effects come into play. These second-order effects will be the main focus of this post. WebUsing measurements and simulations we show that body-bias effect is enhanced as the gate length is decreased. We study the impact of channel doping and device geometry on body-bias effect.
