For capacitive sensing, driving signal with DC bias voltage and ac voltage is usually necessary for the measurement of capacitance.
对电容式加速度计,为测量其电容的变化,通常需要带直流偏置的交流电压信号来驱动。

The novel design solved the problem of limited voltage swing range caused by bias voltage at input of the OPA and achieved higher bandwidth compared to ac coupled design method.
Then analyzed the relationship between Attribution Complexity (AC) and the general attitude of prejudice and the Bias Blind Spot (BBS) through two experimental studies.
