程控增益线性脉冲放大器的设计

The design of programme-controlled gain and linear pulse amplifier

设计了一种新型程控增益线性脉冲放大器。采用准高斯CR-RC-CR成形电路结构,使用非易失性数字电位器和精密运放,使电路结构大大简化,抗干扰能力强,增益多级连续变化平稳,且具有温漂低、脉冲线性好等特点。

We have designed a kind of new-style programme-controlled gain and linear pulse amplifier with accurate gausses of CR-RC-CR shaping circuit structure. The use of nonvolatile digital electric potential device and accurate operational amplifier makes the circuit structure simple greatly, makes the ability stronger that resists assault. It can realize multistage gain in succession and make the drift of temperature low and make the linearity of pulse well.
