摘要
设备的冲击和振动信号常用压电加速度传感器来获取。压电加速度传感器是高内阻传感器,仅能输出微弱的电荷信号,需要使用电荷放大器对电荷进行电荷-电压转换,方便后续的放大和处理。本文对电荷放大电路进行研究,进而提出基于AD8601的电荷放大器的设计方法。
Piezoelectric acceleration sensor is a high internal-impedenee device and the output of the device is low charge signal, which need taking a charge amplifier to transform the charge to voltage to facilitate subsequent amplification and processing. Therefore, this paper focuses on the charge circuit, and put forward a design based on AD8601.
