Title of Achievement:“一种用于调频连续波激光雷达系统的新型平衡探测光电前端电路”(A Novel Balanced Detection Based ptoelectronic Front End Circuit for FMCW LiDAR System)
Note:本文提出了一种基于硅基平衡探测器的新型激光雷达芯片系统,通过光电融合设计提升了光电探测灵敏度、并消除传统测距系统中噪声和寄生贡献较大的冗余光电二极管以扩展测距范围。所提的模拟前端电路芯片采用前置跨阻放大器实现光电流到电压信号转换,并采用两级后级可变增益放大器实现动态范围拓展。该项工作在40nm工艺下流片,面积仅占0.086 mm2,工作电压为1.1 V,在132MHz的信号带宽下电路最大增益可达100 dBΩ,动态范围为66.2 dB,设计指标达到国际学术界领先水平。
