该转换器的高输入阻抗和低失调电压漂移输入增益级可以保证芯片在微弱电压信号下正常工作。

The designed converter could operate well with a slender supply voltage signal because of its high input resistance and low offset drift.

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。

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.
