中文摘要：

设计了一款用于红外通信中的I-V转换电路，该电路包含了一个跨阻放大器和两个补偿结构。直流补偿电路用来补偿由环境光产生的直流光电流，避免后级电路出现饱和；交流补偿电路用来提高输入交流阻抗，从而保持电路对输入信号的灵敏度。研究表明，通过对I-V转换电路实现双补偿，整体电路的增益控制及灵敏度均有显著提高。该电路采用VIS 0.6μm BiCMOS工艺进行设计与流片，在3 V工作电压下，对10 nA到300μA的直流光电流具有良好的抑制能力，使电路的增益恒定在110 dB ，具有良好的稳定性。

英文摘要：

An I-V converter circuit was designed by using the infrared communication. The converter circuit contained a transimpedance amplifier and two compensation structures. The DC compensation circuit was used to compensate the DC photocurrent generated by ambient light and prevent the saturation at later stages. The AC compensation circuit was used to improve the AC input impedance and preserve the sensitivity of the signal of interest. The research shows, through the I-V conversion circuit to realize the double compensation, the gain control of the circuit and sensitivity are improved significantly. This circuit is implemented in the 0.6 μm BiCMOS process. Operating under 3 V, it achieved a DC photocurrent rejection ranging from 10 nA to 300 μA and the gain obtained with 110 dB with a good stability.
