The Design of Internal Preamplifier Set in Acoustics Sensor

根据所述声传感器内藏式前置放大器的特点,提出了低噪声性能设计中的必须兼及动态范围新观点.提供了一种优质声传感器内藏式前置放大器实例.

This paper describes the features and designing mathod for internal preampli-fier set in acoustics sensor. The new point of view for disign which expanding dynamicrange and reducing noise must be given attention is presented. At last, a practical exam-ple for internal preamplifier set in acoustics sensor with high guality is provided.
