The MOSFET input diode is controlled by an electric field in the gate region, thus the input impedance is always extremely high because there is no forward biased diode to lower the input impedance.

提出了两种模拟二极管正向导通输入输出特性的数学函数,进行数字序列峰值因数的控制。
Two input-output soft-clip functions that mimic the diode full-wave soft clipping have been designed to control the peak factor of digital sequences.

而C1的正向不能立即改变极性,其被拉低并通过输入的内部上拉电阻,缓慢的再次充电。
Because the positive side of C1 cannot instantly change its polarity, it pulls low and slowly charges up again through the internal pullup resistor of the input.
