▎ 摘　　要

In the above paper, Iannazzo et al. propose an improvement of the compact model by introducing a new expression for the description of the bias-dependent saturation velocity. They compare their model to simulation results using the compact model. We comment on this paper, since Iannazzo et al. use inappropriate parameter values for the compact model. We further show that with suitable parameter values, the results from both models are very close.
