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
