Abstract
Charge injection error in the presence of subthreshold effects has been analyzed. It is confirmed that the subthreshold effect is significant at low voltage falling rates. A simplified model is derived using an appropriate approximation. Predictions are compared to the results of a SPICE simulation, a nonquasi-static (NQS) model simulation and experimental results. Excellent agreement between the modified and NQS model and recently published experimental results was obtained. This analytical model is computationally efficient compared to the SPICE and NQS models and provides physical insight into the switching errors.
