This model is superior to Statz and Angelov models in describing the strong nonlinear Cgs in the low Vds area and it has less calculations than the numerical models based on physics of devices, therefore suitable for design and optimization of circuits.

• 为了进一步提高模型精度，依据实验数据对理论模型中一些敏感参数进行优化，使之在全域范围内精确反映电容变化规律，并且比较了理论和优化模型的特点。
