摘要
针对传统放大电路设计出了一种用于红外光电立靶测试系统的前置放大器的电路,在设计中选用低噪声运算放大器和仪表放大器组成电路,同时论述了关于低噪声放大电路设计中的屏蔽和接地措施。
Focused on the problem of conventional way, a design of preamplifier was brought forward in testing system intensive degree photoelectric target. In the design, low noise amplifier and instrument amplifier are used. Measures of shield and grounding were discussed.
