摘要

这封信展示了一种低噪声线性跨阻放大器（TIA），用于 0.13- $\mu $ m SiGe BiCMOS 单端相干光接收器（ORX）。该 TIA 采用改进型分路反馈 (SFB) 高 $R_{F}$ TIA 内核的级联结构，该内核针对高线性度进行了优化，同时还采用了具有可调峰值的可变增益单到差分 (VG-S2D) 电路，从而在宽增益动态范围内实现了相对较低的噪声、出色的线性度和大致不变的带宽 (BW)。TIA 的测量结果显示，在 74-dB $\Omega $ 最大跨导增益 $(Z_{T}) {_{,}}~37$ -dB 增益动态范围内，具有 42-GHz -3-dB BW、12.5-pA/ $\sqrt {\mathrm {(Hz)}}$ 输入参考噪声 (IRN) 电流密度和 $2{^{{31}} 。｝-1$ .TIA 采用 3.3 V 电压供电，电流为 72 mA，所有测试焊盘占用芯片面积为 1 mm2。
