一种大动态高速微弱脉冲信号的线性测量电路
摘要：
本发明公开了一种大动态高速微弱脉冲信号的线性测量电路。它包括光电探测器、前置流压转换电路、高速积分电路、峰值保持电路、低频电压放大电路和AD采用电路；光电探测器与前置流压转换电路、高速积分电路、峰值保持电路、低频电压放大电路和AD采用电路依次相连。本发明设计合理、性能稳定，提供了一种大动态高速微弱脉冲信号的线性测量电路。本发明中的峰值保持电路用了一般的峰值保持电路，能够对较慢的信号进行有效的保持；本发明中仍然采取切换量程的方式来，这样能够达到扩展量程的目的，在不切换通道的同时能够达到30dB以上的动态测量范围。
摘要（英）：

The present invention discloses a large dynamic high speed weak pulse signal linear measuring circuit. The circuit comprises a photoelectric detector, a prepositive current pressure conversion circuit, a high speed integrating circuit, a peak holding circuit, a low frequency voltage amplifying circuit and an AD sampling circuit; wherein the photoelectric detector is sequentially connected with the prepositive current pressure conversion circuit, the high speed integrating circuit, the peak holding circuit, the low frequency voltage amplifying circuit and the AD sampling circuit. The present invention has reasonable design and stable performance and provides a large dynamic high speed weak pulse signal linear measuring circuit. A common peak holding circuit is adopted in the present invention, slower signal can be effectively held; measuring range switching manner is still adopted, thus the aim of expanding measuring range can be achieved; and dynamic measuring range of more than 30dB can be achieved without switching channel.
