低频低噪声高增益放大器的设计与研究

Design and Study on an Amplifier with low Frequency,Low Noise and High Gain

本设计制作的是一个低频低噪声、高增益放大器。它是利用单片机对整个电路进行控制。主要优点失真小,放大倍数高以及增益大小可编程控制。

This amplifier with low frequency,low noise and high gain has been designed and fabricated.All the circuits are controlled by a single-chip microcomputer.Its main advantages are low distortion and high magnification times.In addition,its gain magnitude can be controlled through programming.
