We propose an ac-coupled amplifier that offers a high input impedance, thus making it suitable for bioelectric signal amplification. We also present the necessary formulas for calculating its input impedance and transfer function in order to facilitate its adaptation to different applications.
我们提出了一种交流耦合放大器，它具有高输入阻抗，因此适用于生物电信号放大。我们还给出了计算其输入阻抗和传递函数的必要公式，以便于其适应不同的应用。
