    Threshold voltage model

    Vth对器件操作有三种操作区:

    Vg>>Vth in strong inversion region, drift current is dominant.

    Vg<<Vth in weak inversion region, diffusion current is dominant.

    Vg≈Vth in moderate inversion region, both drift and diffusion current are important.

    Ps: drift 漂移;diffusion 扩散

    漂移是在电场作用下的运动;扩散是在浓度差驱使下的运动
