摘要
本文提出了一种高精度数控增益自寻优放大器，并给出了由其构成宽动态范围输入信号实时数据采集系统的应用实例，克服了常规程控放大数据采集系统实时性较差的缺陷，并使得模数转换器对小信号的分辨率提高了一个数量级，从而提高了数据采集系统的精度和速度。
This paper puts forward a high precision gain self optimizing amplifier based on digital-control, and presents an exampl of real-time data acquistion system. It gets rid of the weakness of real-time performance of data acquisitionsystem based on normal programmable-gain-amplifier, and increases the resolution of A/D converter up to 1 order of magnitude for weak signal and enhances the precision and the velocity of the data acquisition system.
