It is also demonstrated that the AGC systems with exponential gain control characteristic may strictly be transformed into a linear system by using any logarithmic amplifier.

在比较器和受控放大器之间接上一个对数放大器，就可以使增益控制特性为指数函数的AGC系统严格线性化。

It consists of a variable-gain cell based on a current-steering structure, a novel wide-range exponential voltage generator, and a stage of a fixed-gain amplifier.

该放大器由电流调节型可变增益单元、宽范围指数电压转换电路及固定增益放大器构成。
