MP3/PDA/数字录音笔/数码相机上用到的低成本音频AGC电路的应用

在电子电路中，为提高系统的性能，广泛采用具有自动调节作用的控制电路，如自动增益控制(AGC)电路、自动频率控制(AFC)电路和自动相位控制(APC)电路。

介绍一个低成本音频AGC电路的好技术方案应用，该方案比普通的设计方案更加低成本，且效果更佳。

In the early years of radio circuits, fading (defined as slow variations in the amplitude of the received signals) required continuing adjustments in the receiver’s gain in order to maintain a relative constant output signal. Such situation led to the design of circuits, which primary ideal function was to maintain a constant signal level at the output, regardless of the signal’s variations at the input of the system. Originally, those circuits were described as automatic volume control circuits, a few years later they were generalized under the name of Automatic Gain Control (AGC) circuits [1,2].
